+.SYNOPSIS
+    Validates that a Monaco Editor update was performed correctly.
+
+.DESCRIPTION
+    Runs a series of checks against the Monaco Editor files in the repository
+    to ensure the update is valid and no regressions were introduced.
+
+    Tests:
+      - loader.js exists and contains version info
+      - monaco_languages.json is valid JSON with expected structure
+      - All expected built-in Monaco languages are present
+      - All PowerToys custom languages are registered
+      - Custom language extension mappings are present
+      - Monaco directory structure is intact
+      - No empty/corrupt core files
+
+.PARAMETER RepoRoot
+    The root of the PowerToys repository. Defaults to the repo root
+    relative to this script.

+
+# WinMD API Search
+
+This skill helps you find the right Windows API for any capability and get its full details. It searches a local cache of all WinMD metadata from:
+
+- **Windows Platform SDK** — all `Windows.*` WinRT APIs (always available, no restore needed)
+- **WinAppSDK / WinUI** — bundled as a baseline in the cache generator (always available, no restore needed)
+- **NuGet packages** — any additional packages in restored projects that contain `.winmd` files
+- **Project-output WinMD** — class libraries (C++/WinRT, C#) that produce `.winmd` as build output
+
+Even on a fresh clone with no restore or build, you still get full Platform SDK + WinAppSDK coverage.
+
+## When to Use This Skill
+
+- User wants to build a feature and you need to find which API provides that capability
+- User asks "how do I do X?" where X involves a platform feature (camera, files, notifications, sensors, AI, etc.)
+- You need the exact methods, properties, events, or enumeration values of a type before writing code
+- You're unsure which control, class, or interface to use for a UI or system task
+
+## Prerequisites
+
+- **.NET SDK 8.0 or later** — required to build the cache generator. Install from [dotnet.microsoft.com](https://dotnet.microsoft.com/download) if not available.
+
+## Cache Setup (Required Before First Use)
+
+All query and search commands read from a local JSON cache. **You must generate the cache before running any queries.**
+
+```powershell
+# All projects in the repo (recommended for first run)
+.\.github\skills\winmd-api-search\scripts\Update-WinMdCache.ps1
+
+# Single project
+.\.github\skills\winmd-api-search\scripts\Update-WinMdCache.ps1 -ProjectDir <project-folder>
+```
+
+No project restore or build is needed for baseline coverage (Platform SDK + WinAppSDK). For additional NuGet packages, the project needs `dotnet restore` (which generates `project.assets.json`) or a `packages.config` file.
+
+Cache is stored at `Generated Files\winmd-cache\`, deduplicated per-package+version.
+
+### What gets indexed
+
+| Source | When available |
+|--------|----------------|
+| Windows Platform SDK | Always (reads from local SDK install) |
+| WinAppSDK (latest) | Always (bundled as baseline in cache generator) |
+| WinAppSDK Runtime | When installed on the system (detected via `Get-AppxPackage`) |
+| Project NuGet packages | After `dotnet restore` or with `packages.config` |
+| Project-output `.winmd` | After project build (class libraries that produce WinMD) |
+
+> **Note:** This cache directory should be in `.gitignore` — it's generated, not source.
+
+## How to Use
+
+Pick the path that matches the situation:
+
+---
+
+### Discover — "I don't know which API to use"
+
+The user describes a capability in their own words. You need to find the right API.
+
+**0. Ensure the cache exists**
+
+If the cache hasn't been generated yet, run `Update-WinMdCache.ps1` first — see [Cache Setup](#cache-setup-required-before-first-use) above.
+
+**1. Translate user language → search keywords**
+
+Map the user's daily language to programming terms. Try multiple variations:
+
+| User says | Search keywords to try (in order) |
+|-----------|-----------------------------------|
+| "take a picture" | `camera`, `capture`, `photo`, `MediaCapture` |
+| "load from disk" | `file open`, `picker`, `FileOpen`, `StorageFile` |
+| "describe what's in it" | `image description`, `Vision`, `Recognition` |
+| "show a popup" | `dialog`, `flyout`, `popup`, `ContentDialog` |
+| "drag and drop" | `drag`, `drop`, `DragDrop` |
+| "save settings" | `settings`, `ApplicationData`, `LocalSettings` |
+
+Start with simple everyday words. If results are weak or irrelevant, try the more technical variation.
+
+**2. Run searches**
+
+```powershell
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action search -Query "<keyword>"
+```
+
+This returns ranked namespaces with top matching types and the **JSON file path**.
+
+If results have **low scores (below 60) or are irrelevant**, fall back to searching online documentation:
+
+1. Use web search to find the right API on Microsoft Learn, for example:
+   - `site:learn.microsoft.com/uwp/api <capability keywords>` for `Windows.*` APIs
+   - `site:learn.microsoft.com/windows/windows-app-sdk/api/winrt <capability keywords>` for `Microsoft.*` WinAppSDK APIs
+2. Read the documentation pages to identify which type matches the user's requirement.
+3. Once you know the type name, come back and use `-Action members` or `-Action enums` to get the exact local signatures.
+
+**3. Read the JSON to choose the right API**
+
+Read the file at the path(s) from the top results. The JSON has all types in that namespace — full members, signatures, parameters, return types, enumeration values.
+
+Read and decide which types and members fit the user's requirement.
+
+**4. Look up official documentation for context**
+
+The cache contains only signatures — no descriptions or usage guidance. For explanations, examples, and remarks, look up the type on Microsoft Learn:
+
+| Namespace prefix | Documentation base URL |
+|-----------------|----------------------|
+| `Windows.*` | `https://learn.microsoft.com/uwp/api/{fully.qualified.typename}` |
+| `Microsoft.*` (WinAppSDK) | `https://learn.microsoft.com/windows/windows-app-sdk/api/winrt/{fully.qualified.typename}` |
+
+For example, `Microsoft.UI.Xaml.Controls.NavigationView` maps to:
+`https://learn.microsoft.com/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.navigationview`
+
+**5. Use the API knowledge to answer or write code**
+
+---
+
+### Lookup — "I know the API, show me the details"
+
+You already know (or suspect) the type or namespace name. Go direct:
+
+```powershell
+# Get all members of a known type
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action members -TypeName "Microsoft.UI.Xaml.Controls.NavigationView"
+
+# Get enum values
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action enums -TypeName "Microsoft.UI.Xaml.Visibility"
+
+# List all types in a namespace
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action types -Namespace "Microsoft.UI.Xaml.Controls"
+
+# Browse namespaces
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action namespaces -Filter "Microsoft.UI"
+```
+
+If you need full detail beyond what `-Action members` shows, use `-Action search` to get the JSON file path, then read the JSON file directly.
+
+---
+
+### Other Commands
+
+```powershell
+# List cached projects
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action projects
+
+# List packages for a project
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action packages
+
+# Show stats
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action stats
+```
+
+> If only one project is cached, `-Project` is auto-selected.
+> If multiple projects exist, add `-Project <name>` (use `-Action projects` to see available names).
+> In scan mode, manifest names include a short hash suffix to avoid collisions; you can pass the base project name without the suffix if it's unambiguous.
+
+## Search Scoring
+
+The search ranks type names and member names against your query:
+
+| Score | Match type | Example |
+|-------|-----------|---------|
+| 100 | Exact name | `Button` → `Button` |
+| 80 | Starts with | `Navigation` → `NavigationView` |
+| 60 | Contains | `Dialog` → `ContentDialog` |
+| 50 | PascalCase initials | `ASB` → `AutoSuggestBox` |
+| 40 | Multi-keyword AND | `navigation item` → `NavigationViewItem` |
+| 20 | Fuzzy character match | `NavVw` → `NavigationView` |
+
+Results are grouped by namespace. Higher-scored namespaces appear first.
+
+## Troubleshooting
+
+| Issue | Fix |
+|-------|-----|
+| "Cache not found" | Run `Update-WinMdCache.ps1` |
+| "Multiple projects cached" | Add `-Project <name>` |
+| "Namespace not found" | Use `-Action namespaces` to list available ones |
+| "Type not found" | Use fully qualified name (e.g., `Microsoft.UI.Xaml.Controls.Button`) |
+| Stale after NuGet update | Re-run `Update-WinMdCache.ps1` |
+| Cache in git history | Add `Generated Files/` to `.gitignore` |

+.SYNOPSIS
+    Generate or refresh the WinMD cache for the Agent Skill.
+
+.DESCRIPTION
+    Builds and runs the standalone cache generator to export cached JSON files
+    from all WinMD metadata found in project NuGet packages and Windows SDK.
+
+    The cache is per-package+version: if two projects reference the same
+    package at the same version, the WinMD data is parsed once and shared.
+
+    Supports single project or recursive scan of an entire repo.
+
+.PARAMETER ProjectDir
+    Path to a project directory (contains .csproj/.vcxproj), or a project file itself.
+    Defaults to scanning the workspace root.
+
+.PARAMETER Scan
+    Recursively discover all .csproj/.vcxproj files under ProjectDir.
+
+.PARAMETER OutputDir
+    Path to the cache output directory. Defaults to "Generated Files\winmd-cache".
+

+# WPF to WinUI 3 Migration Skill
+
+Migrate PowerToys modules from WPF (`System.Windows.*`) to WinUI 3 (`Microsoft.UI.Xaml.*` / Windows App SDK). Based on patterns validated in the ImageResizer module migration.
+
+## When to Use This Skill
+
+- Migrate a PowerToys module from WPF to WinUI 3
+- Convert WPF XAML files to WinUI 3 XAML
+- Replace `System.Windows` namespaces with `Microsoft.UI.Xaml`
+- Migrate `Dispatcher` usage to `DispatcherQueue`
+- Migrate custom `Observable`/`RelayCommand` to CommunityToolkit.Mvvm source generators
+- Replace WPF-UI (Lepo) controls with native WinUI 3 controls
+- Convert imaging code from `System.Windows.Media.Imaging` to `Windows.Graphics.Imaging`
+- Handle WPF `Window` vs WinUI `Window` differences (sizing, positioning, SizeToContent)
+- Migrate resource files from `.resx` to `.resw` with `ResourceLoader`
+- Fix installer/build pipeline issues after WinUI 3 migration
+- Update project files, NuGet packages, and signing config
+
+## Prerequisites
+
+- Visual Studio 2022 17.4+
+- Windows App SDK NuGet package (`Microsoft.WindowsAppSDK`)
+- .NET 8+ with `net8.0-windows10.0.19041.0` TFM
+- Windows 10 1803+ (April 2018 Update or newer)
+
+## Migration Strategy
+
+### Recommended Order
+
+1. **Project file** — Update TFM, NuGet packages, set `<UseWinUI>true</UseWinUI>`
+2. **Data models and business logic** — No UI dependencies, migrate first
+3. **MVVM framework** — Replace custom Observable/RelayCommand with CommunityToolkit.Mvvm
+4. **Resource strings** — Migrate `.resx` → `.resw`, introduce `ResourceLoaderInstance`
+5. **Services and utilities** — Replace `System.Windows` types, async-ify imaging code
+6. **ViewModels** — Update Dispatcher usage, binding patterns
+7. **Views/Pages** — Starting from leaf pages with fewest dependencies
+8. **Main page / shell** — Last, since it depends on everything
+9. **App.xaml / startup code** — Merge carefully (do NOT overwrite WinUI 3 boilerplate)
+10. **Installer & build pipeline** — Update WiX, signing, build events
+11. **Tests** — Adapt for WinUI 3 runtime, async patterns
+
+### Key Principles
+
+- **Do NOT overwrite `App.xaml` / `App.xaml.cs`** — WinUI 3 has different application lifecycle boilerplate. Merge your resources and initialization code into the generated WinUI 3 App class.
+- **Do NOT create Exe→WinExe `ProjectReference`** — Extract shared code to a Library project. This causes phantom build artifacts.
+- **Use `Lazy<T>` for resource-dependent statics** — `ResourceLoader` is not available at class-load time in all contexts.
+
+## Quick Reference Tables
+
+### Namespace Mapping
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `System.Windows` | `Microsoft.UI.Xaml` |
+| `System.Windows.Controls` | `Microsoft.UI.Xaml.Controls` |
+| `System.Windows.Media` | `Microsoft.UI.Xaml.Media` |

+
+### Critical API Replacements
+
+| WPF | WinUI 3 | Notes |
+|-----|---------|-------|
+| `Dispatcher.Invoke()` | `DispatcherQueue.TryEnqueue()` | Different return type (`bool`) |
+| `Dispatcher.CheckAccess()` | `DispatcherQueue.HasThreadAccess` | Property vs method |
+| `Application.Current.Dispatcher` | Store `DispatcherQueue` in static field | See [Threading](./references/threading-and-windowing.md) |
+| `MessageBox.Show()` | `ContentDialog` | Must set `XamlRoot` |
+| `DynamicResource` | `ThemeResource` | Theme-reactive only |
+| `clr-namespace:` | `using:` | XAML namespace prefix |
+| `{x:Static props:Resources.Key}` | `x:Uid` or `ResourceLoader.GetString()` | .resx → .resw |
+| `DataType="{x:Type m:Foo}"` | Remove or use code-behind | `x:Type` not supported |
+| `Properties.Resources.MyString` | `ResourceLoaderInstance.ResourceLoader.GetString("MyString")` | Lazy-init pattern |
+| `Application.Current.MainWindow` | Custom `App.Window` static property | Must track manually |

+| `encoder.QualityLevel = 85` | `BitmapPropertySet { "ImageQuality", 0.85f }` | int 1-100 → float 0-1 |
+
+### NuGet Package Migration
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `Microsoft.Xaml.Behaviors.Wpf` | `Microsoft.Xaml.Behaviors.WinUI.Managed` |
+| `WPF-UI` (Lepo) | Remove — use native WinUI 3 controls |
+| `CommunityToolkit.Mvvm` | `CommunityToolkit.Mvvm` (same) |
+| `Microsoft.Toolkit.Wpf.*` | `CommunityToolkit.WinUI.*` |
+| (none) | `Microsoft.WindowsAppSDK` |
+| (none) | `Microsoft.Windows.SDK.BuildTools` |
+| (none) | `WinUIEx` (optional, for window helpers) |
+| (none) | `CommunityToolkit.WinUI.Converters` |
+
+### XAML Syntax Changes
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `xmlns:local="clr-namespace:MyApp"` | `xmlns:local="using:MyApp"` |
+| `{DynamicResource Key}` | `{ThemeResource Key}` |

+| `{x:Type local:MyType}` | Not supported |
+| `<Style.Triggers>` / `<DataTrigger>` | `VisualStateManager` |
+| `{Binding}` in `Setter.Value` | Not supported — use `StaticResource` |
+| `Content="{x:Static p:Resources.Cancel}"` | `x:Uid="Cancel"` with `.Content` in `.resw` |
+| `<ui:FluentWindow>` / `<ui:Button>` (WPF-UI) | Native `<Window>` / `<Button>` |
+| `<ui:NumberBox>` / `<ui:ProgressRing>` (WPF-UI) | Native `<NumberBox>` / `<ProgressRing>` |
+| `BasedOn="{StaticResource {x:Type ui:Button}}"` | `BasedOn="{StaticResource DefaultButtonStyle}"` |
+| `IsDefault="True"` / `IsCancel="True"` | `Style="{StaticResource AccentButtonStyle}"` / handle via KeyDown |
+| `<AccessText>` | Not available — use `AccessKey` property |
+| `<behaviors:Interaction.Triggers>` | Migrate to code-behind or WinUI behaviors |

+## Common Pitfalls (from ImageResizer migration)
+
+| Pitfall | Solution |
+|---------|----------|
+| `ContentDialog` throws "does not have a XamlRoot" | Set `dialog.XamlRoot = this.Content.XamlRoot` before `ShowAsync()` |
+| `FilePicker` throws error in desktop app | Call `WinRT.Interop.InitializeWithWindow.Initialize(picker, hwnd)` |
+| `Window.Dispatcher` returns null | Use `Window.DispatcherQueue` instead |
+| Resources on `Window` element not found | Move resources to root layout container (`Grid.Resources`) |
+| `VisualStateManager` on `Window` fails | Use `UserControl` or `Page` inside the Window |
+| Satellite assembly installer errors (`WIX0103`) | Remove `.resources.dll` refs from `Resources.wxs`; WinUI 3 uses `.pri` |
+| Phantom `.exe`/`.deps.json` in root output dir | Avoid Exe→WinExe `ProjectReference`; use Library project |
+| `ResourceLoader` crash at static init | Wrap in `Lazy<T>` or null-coalescing property — see [Lazy Init](./references/powertoys-patterns.md#lazy-initialization-for-resource-dependent-statics) |
+| `SizeToContent` not available | Implement manual content measurement + `AppWindow.Resize()` with DPI scaling |
+| `x:Bind` default mode is `OneTime` | Explicitly set `Mode=OneWay` or `Mode=TwoWay` |
+| `DynamicResource` / `x:Static` not compiling | Replace with `ThemeResource` / `ResourceLoader` or `x:Uid` |
+| `IValueConverter.Convert` signature mismatch | Last param: `CultureInfo` → `string` (language tag) |
+| Test project can't resolve WPF types | Add `<UseWPF>true</UseWPF>` temporarily; remove after imaging migration |
+| Pixel dimension type mismatch (`int` vs `uint`) | WinRT uses `uint` for pixel sizes — add `u` suffix in test assertions |
+| `$(SolutionDir)` empty in standalone project build | Use `$(MSBuildThisFileDirectory)` with relative paths instead |
+| JPEG quality value wrong after migration | WPF: int 1-100; WinRT: float 0.0-1.0 |
+| MSIX packaging fails in PreBuildEvent | Move to PostBuildEvent; artifacts not ready at PreBuild time |
+| RC file icon path with forward slashes | Use double-backslash escaping: `..\\ui\\Assets\\icon.ico` |
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Build fails after namespace rename | Check for lingering `System.Windows` usings; some types have no direct equivalent |
+| Missing `PresentationCore.dll` at runtime | Ensure ALL imaging code uses `Windows.Graphics.Imaging`, not `System.Windows.Media.Imaging` |
+| `DataContext` not working on Window | WinUI 3 `Window` is not a `DependencyObject`; use a root `Page` or `UserControl` |
+| XAML designer not available | WinUI 3 does not support XAML Designer; use Hot Reload instead |
+| NuGet restore failures | Run `build-essentials.cmd` after adding `Microsoft.WindowsAppSDK` package |
+| `Parallel.ForEach` compilation error | Migrate to `Parallel.ForEachAsync` for async imaging operations |
+| Signing check fails on leaked artifacts | Run `generateAllFileComponents.ps1`; verify only `WinUI3Apps\\` paths in signing config |

+# Imaging API Migration
+
+Migrating from WPF (`System.Windows.Media.Imaging` / `PresentationCore.dll`) to WinRT (`Windows.Graphics.Imaging`). Based on the ImageResizer migration.
+
+## Why This Migration Is Required
+
+WinUI 3 apps deployed as self-contained do NOT include `PresentationCore.dll`. Any code using `System.Windows.Media.Imaging` will throw `FileNotFoundException` at runtime. ALL imaging code must use WinRT APIs.
+
+| Purpose | Namespace |
+|---------|-----------|
+| UI display (`Image.Source`) | `Microsoft.UI.Xaml.Media.Imaging` |
+| Image processing (encode/decode/transform) | `Windows.Graphics.Imaging` |
+
+## Architecture Change: Pipeline vs Declarative
+
+The fundamental architecture differs:
+
+**WPF**: In-memory pipeline of bitmap objects. Decode → transform → encode synchronously.
+```csharp
+var decoder = BitmapDecoder.Create(stream, ...);
+var transform = new TransformedBitmap(decoder.Frames[0], new ScaleTransform(...));
+var encoder = new JpegBitmapEncoder();
+encoder.Frames.Add(BitmapFrame.Create(transform, ...));
+encoder.Save(outputStream);
+```
+
+**WinRT**: Declarative transform model. Configure transforms on the encoder, which handles pixel manipulation internally. All async.
+```csharp
+var decoder = await BitmapDecoder.CreateAsync(winrtStream);
+var encoder = await BitmapEncoder.CreateForTranscodingAsync(outputStream, decoder);
+encoder.BitmapTransform.ScaledWidth = newWidth;
+encoder.BitmapTransform.ScaledHeight = newHeight;
+encoder.BitmapTransform.InterpolationMode = BitmapInterpolationMode.Fant;
+await encoder.FlushAsync();
+```
+
+## Core Type Mapping
+
+### Decoders
+
+| WPF | WinRT | Notes |
+|-----|-------|-------|
+| `BitmapDecoder.Create(stream, options, cache)` | `BitmapDecoder.CreateAsync(stream)` | Async, auto-detects format |
+| `JpegBitmapDecoder` / `PngBitmapDecoder` / etc. | `BitmapDecoder.CreateAsync(stream)` | Single unified decoder |
+| `decoder.Frames[0]` | `await decoder.GetFrameAsync(0)` | Async frame access |
+| `decoder.Frames.Count` | `decoder.FrameCount` (uint) | `int` → `uint` |
+| `decoder.CodecInfo.ContainerFormat` | `decoder.DecoderInformation.CodecId` | Different property path |
+| `decoder.Frames[0].PixelWidth` (int) | `decoder.PixelWidth` (uint) | `int` → `uint` |
+| `WmpBitmapDecoder` | Not available | WMP/HDP not supported |
+
+### Encoders
+
+| WPF | WinRT | Notes |
+|-----|-------|-------|
+| `new JpegBitmapEncoder()` | `BitmapEncoder.CreateAsync(BitmapEncoder.JpegEncoderId, stream)` | Async factory |
+| `new PngBitmapEncoder()` | `BitmapEncoder.CreateAsync(BitmapEncoder.PngEncoderId, stream)` | No interlace control |
+| `encoder.Frames.Add(frame)` | `encoder.SetSoftwareBitmap(bitmap)` | Different API |
+| `encoder.Save(stream)` | `await encoder.FlushAsync()` | Async |
+
+### Encoder Properties (Strongly-Typed → BitmapPropertySet)
+
+WPF had type-specific encoder subclasses. WinRT uses a generic property set:
+
+```csharp
+// WPF
+case JpegBitmapEncoder jpeg: jpeg.QualityLevel = 85;        // int 1-100
+case PngBitmapEncoder png:   png.Interlace = PngInterlaceOption.On;
+case TiffBitmapEncoder tiff: tiff.Compression = TiffCompressOption.Lzw;
+
+// WinRT — JPEG quality (float 0.0-1.0)
+await encoder.BitmapProperties.SetPropertiesAsync(new BitmapPropertySet
+{
+    { "ImageQuality", new BitmapTypedValue(0.85f, PropertyType.Single) }
+});
+
+// WinRT — TIFF compression (via BitmapPropertySet at creation time)
+var props = new BitmapPropertySet
+{
+    { "TiffCompressionMethod", new BitmapTypedValue((byte)2, PropertyType.UInt8) }
+};
+var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.TiffEncoderId, stream, props);
+```
+
+**JPEG quality scale change**: WPF int `1-100` → WinRT float `0.0-1.0`. Divide by 100.
+
+### Bitmap Types
+
+| WPF | WinRT | Notes |
+|-----|-------|-------|
+| `BitmapSource` | `SoftwareBitmap` | Central pixel-data type |
+| `BitmapImage` | `BitmapImage` (in `Microsoft.UI.Xaml.Media.Imaging`) | UI display only |
+| `FormatConvertedBitmap` | `SoftwareBitmap.Convert()` | |
+| `TransformedBitmap` + `ScaleTransform` | `BitmapTransform` via encoder | Declarative |
+| `CroppedBitmap` | `BitmapTransform.Bounds` | |
+
+### Metadata
+
+| WPF | WinRT | Notes |
+|-----|-------|-------|
+| `BitmapMetadata` | `BitmapProperties` | Different API surface |
+| `BitmapMetadata.Clone()` | No equivalent | Cannot selectively clone |
+| Selective metadata removal | Not supported | All-or-nothing only |
+
+**Two encoder creation strategies for metadata:**
+- `CreateForTranscodingAsync()` — preserves ALL metadata from source
+- `CreateAsync()` — creates fresh encoder with NO metadata
+
+This eliminated ~258 lines of manual metadata manipulation code (`BitmapMetadataExtension.cs`) in ImageResizer.
+
+### Interpolation Modes
+
+| WPF `BitmapScalingMode` | WinRT `BitmapInterpolationMode` |
+|------------------------|-------------------------------|
+| `HighQuality` / `Fant` | `Fant` |
+| `Linear` | `Linear` |
+| `NearestNeighbor` | `NearestNeighbor` |
+| `Unspecified` / `LowQuality` | `Linear` |
+
+## Stream Interop
+
+WinRT imaging requires `IRandomAccessStream` instead of `System.IO.Stream`:
+
+```csharp
+using var stream = File.OpenRead(path);
+var winrtStream = stream.AsRandomAccessStream();  // Extension method
+var decoder = await BitmapDecoder.CreateAsync(winrtStream);
+```
+
+**Critical**: For transcode, seek the input stream back to 0 before creating the encoder:
+```csharp
+winrtStream.Seek(0);
+var encoder = await BitmapEncoder.CreateForTranscodingAsync(outputStream, decoder);
+```
+
+## CodecHelper Pattern (from ImageResizer)
+
+WPF stored container format GUIDs in `settings.json`. WinRT uses different codec IDs. Create a `CodecHelper` to bridge them:
+
+```csharp
+internal static class CodecHelper
+{
+    // Maps WPF container format GUIDs (stored in settings JSON) to WinRT encoder IDs
+    private static readonly Dictionary<Guid, Guid> LegacyGuidToEncoderId = new()
+    {
+        [new Guid("19e4a5aa-5662-4fc5-a0c0-1758028e1057")] = BitmapEncoder.JpegEncoderId,
+        [new Guid("1b7cfaf4-713f-473c-bbcd-6137425faeaf")] = BitmapEncoder.PngEncoderId,
+        [new Guid("0af1d87e-fcfe-4188-bdeb-a7906471cbe3")] = BitmapEncoder.BmpEncoderId,
+        [new Guid("163bcc30-e2e9-4f0b-961d-a3e9fdb788a3")] = BitmapEncoder.TiffEncoderId,
+        [new Guid("1f8a5601-7d4d-4cbd-9c82-1bc8d4eeb9a5")] = BitmapEncoder.GifEncoderId,
+    };
+
+    // Maps decoder IDs to corresponding encoder IDs
+    private static readonly Dictionary<Guid, Guid> DecoderIdToEncoderId = new()
+    {
+        [BitmapDecoder.JpegDecoderId] = BitmapEncoder.JpegEncoderId,
+        [BitmapDecoder.PngDecoderId] = BitmapEncoder.PngEncoderId,
+        // ...
+    };
+
+    public static Guid GetEncoderIdFromLegacyGuid(Guid legacyGuid)
+        => LegacyGuidToEncoderId.GetValueOrDefault(legacyGuid, Guid.Empty);
+
+    public static Guid GetEncoderIdForDecoder(BitmapDecoder decoder)
+        => DecoderIdToEncoderId.GetValueOrDefault(decoder.DecoderInformation.CodecId, Guid.Empty);
+}
+```
+
+This preserves backward compatibility with existing `settings.json` files that contain WPF-era GUIDs.
+
+## ImagingEnums Pattern (from ImageResizer)
+
+WPF-specific enums (`PngInterlaceOption`, `TiffCompressOption`) from `System.Windows.Media.Imaging` are used in settings JSON. Create custom enums with identical integer values for backward-compatible deserialization:
+
+```csharp
+// Replace System.Windows.Media.Imaging.PngInterlaceOption
+public enum PngInterlaceOption { Default = 0, On = 1, Off = 2 }
+
+// Replace System.Windows.Media.Imaging.TiffCompressOption
+public enum TiffCompressOption { Default = 0, None = 1, Ccitt3 = 2, Ccitt4 = 3, Lzw = 4, Rle = 5, Zip = 6 }
+```
+
+## Async Migration Patterns
+
+### Method Signatures
+
+All imaging operations become async:
+
+| Before | After |
+|--------|-------|
+| `void Execute(file, settings)` | `async Task ExecuteAsync(file, settings)` |
+| `IEnumerable<Error> Process()` | `async Task<IEnumerable<Error>> ProcessAsync()` |
+
+### Parallel Processing
+
+```csharp
+// WPF (synchronous)
+Parallel.ForEach(Files, new ParallelOptions { MaxDegreeOfParallelism = ... },
+    (file, state, i) => { Execute(file, settings); });
+
+// WinRT (async)
+await Parallel.ForEachAsync(Files, new ParallelOptions { MaxDegreeOfParallelism = ... },
+    async (file, ct) => { await ExecuteAsync(file, settings); });
+```
+
+### CLI Async Bridge
+
+CLI entry points must bridge async to sync:
+```csharp
+return RunSilentModeAsync(cliOptions).GetAwaiter().GetResult();
+```
+
+### Task.Factory.StartNew → Task.Run
+
+```csharp
+// WPF
+_ = Task.Factory.StartNew(StartExecutingWork, token, TaskCreationOptions.LongRunning, TaskScheduler.Default);
+
+// WinUI 3
+_ = Task.Run(() => StartExecutingWorkAsync());
+```
+
+## SoftwareBitmap as Interface Type
+
+When modules expose imaging interfaces (e.g., AI super-resolution), change parameter/return types:
+
+```csharp
+// WPF
+BitmapSource ApplySuperResolution(BitmapSource source, int scale, string filePath);
+
+// WinRT
+SoftwareBitmap ApplySuperResolution(SoftwareBitmap source, int scale, string filePath);
+```
+
+This eliminates manual `BitmapSource ↔ SoftwareBitmap` conversion code (unsafe `IMemoryBufferByteAccess` COM interop).
+
+## MultiFrame Image Handling
+
+```csharp
+// WinRT multi-frame encode (e.g., multi-page TIFF, animated GIF)
+for (uint i = 0; i < decoder.FrameCount; i++)
+{
+    if (i > 0)
+        await encoder.GoToNextFrameAsync();
+
+    var frame = await decoder.GetFrameAsync(i);
+    var bitmap = await frame.GetSoftwareBitmapAsync(
+        frame.BitmapPixelFormat,
+        BitmapAlphaMode.Premultiplied,
+        transform,
+        ExifOrientationMode.IgnoreExifOrientation,
+        ColorManagementMode.DoNotColorManage);
+    encoder.SetSoftwareBitmap(bitmap);
+}
+await encoder.FlushAsync();
+```
+
+## int → uint for Pixel Dimensions
+
+WinRT uses `uint` for all pixel dimensions. This affects:
+- `decoder.PixelWidth` / `decoder.PixelHeight` — `uint`
+- `BitmapTransform.ScaledWidth` / `ScaledHeight` — `uint`
+- `SoftwareBitmap` constructor — `uint` parameters
+- Test assertions: `Assert.AreEqual(96, ...)` → `Assert.AreEqual(96u, ...)`
+
+## Display SoftwareBitmap in UI
+
+```csharp
+var source = new SoftwareBitmapSource();
+// Must convert to Bgra8/Premultiplied for display
+if (bitmap.BitmapPixelFormat != BitmapPixelFormat.Bgra8 ||
+    bitmap.BitmapAlphaMode != BitmapAlphaMode.Premultiplied)
+{
+    bitmap = SoftwareBitmap.Convert(bitmap, BitmapPixelFormat.Bgra8, BitmapAlphaMode.Premultiplied);
+}
+await source.SetBitmapAsync(bitmap);
+myImage.Source = source;
+```
+
+## Known Limitations
+
+| Feature | WPF | WinRT | Impact |
+|---------|-----|-------|--------|
+| PNG interlace | `PngBitmapEncoder.Interlace` | Not available | Always non-interlaced |
+| Metadata stripping | Selective via `BitmapMetadata.Clone()` | All-or-nothing | Orientation EXIF also removed |
+| Pixel formats | Many (`Pbgra32`, `Bgr24`, `Indexed8`, ...) | Primarily `Bgra8`, `Rgba8`, `Gray8/16` | Convert to `Bgra8` |
+| WMP/HDP format | `WmpBitmapDecoder` | Not available | Not supported |
+| Pixel differences | WPF scaler | `BitmapInterpolationMode.Fant` | Not bit-identical |

+# Namespace and API Mapping Reference
+
+Complete reference for mapping WPF types to WinUI 3 equivalents, based on the ImageResizer migration.
+
+## Root Namespace Mapping
+
+| WPF Namespace | WinUI 3 Namespace |
+|---------------|-------------------|
+| `System.Windows` | `Microsoft.UI.Xaml` |
+| `System.Windows.Automation` | `Microsoft.UI.Xaml.Automation` |
+| `System.Windows.Automation.Peers` | `Microsoft.UI.Xaml.Automation.Peers` |
+| `System.Windows.Controls` | `Microsoft.UI.Xaml.Controls` |
+| `System.Windows.Controls.Primitives` | `Microsoft.UI.Xaml.Controls.Primitives` |
+| `System.Windows.Data` | `Microsoft.UI.Xaml.Data` |
+| `System.Windows.Documents` | `Microsoft.UI.Xaml.Documents` |
+| `System.Windows.Input` | `Microsoft.UI.Xaml.Input` |
+| `System.Windows.Markup` | `Microsoft.UI.Xaml.Markup` |
+| `System.Windows.Media` | `Microsoft.UI.Xaml.Media` |
+| `System.Windows.Media.Animation` | `Microsoft.UI.Xaml.Media.Animation` |
+| `System.Windows.Media.Imaging` | `Microsoft.UI.Xaml.Media.Imaging` |
+| `System.Windows.Navigation` | `Microsoft.UI.Xaml.Navigation` |
+| `System.Windows.Shapes` | `Microsoft.UI.Xaml.Shapes` |
+| `System.Windows.Threading` | `Microsoft.UI.Dispatching` |
+| `System.Windows.Interop` | `WinRT.Interop` |
+
+## Core Type Mapping
+
+| WPF Type | WinUI 3 Type |
+|----------|-------------|
+| `System.Windows.Application` | `Microsoft.UI.Xaml.Application` |
+| `System.Windows.Window` | `Microsoft.UI.Xaml.Window` (NOT a DependencyObject) |
+| `System.Windows.DependencyObject` | `Microsoft.UI.Xaml.DependencyObject` |
+| `System.Windows.DependencyProperty` | `Microsoft.UI.Xaml.DependencyProperty` |
+| `System.Windows.FrameworkElement` | `Microsoft.UI.Xaml.FrameworkElement` |
+| `System.Windows.UIElement` | `Microsoft.UI.Xaml.UIElement` |
+| `System.Windows.Visibility` | `Microsoft.UI.Xaml.Visibility` |
+| `System.Windows.Thickness` | `Microsoft.UI.Xaml.Thickness` |
+| `System.Windows.CornerRadius` | `Microsoft.UI.Xaml.CornerRadius` |
+| `System.Windows.Media.Color` | `Windows.UI.Color` (note: `Windows.UI`, not `Microsoft.UI`) |
+| `System.Windows.Media.Colors` | `Microsoft.UI.Colors` |
+
+## Controls Mapping
+
+### Direct Mapping (namespace-only change)
+
+These controls exist in both frameworks with the same name — change `System.Windows.Controls` to `Microsoft.UI.Xaml.Controls`:
+
+`Button`, `TextBox`, `TextBlock`, `ComboBox`, `CheckBox`, `ListBox`, `ListView`, `Image`, `StackPanel`, `Grid`, `Border`, `ScrollViewer`, `ContentControl`, `UserControl`, `Page`, `Frame`, `Slider`, `ProgressBar`, `ToolTip`, `RadioButton`, `ToggleButton`
+
+### Controls With Different Names or Behavior
+
+| WPF | WinUI 3 | Notes |
+|-----|---------|-------|
+| `MessageBox` | `ContentDialog` | Must set `XamlRoot` before `ShowAsync()` |
+| `ContextMenu` | `MenuFlyout` | Different API surface |
+| `TabControl` | `TabView` | Different API |
+| `Menu` | `MenuBar` | Different API |
+| `StatusBar` | Custom `StackPanel` layout | No built-in equivalent |
+| `AccessText` | Not available | Use `AccessKey` property on target control |
+
+### WPF-UI (Lepo) to Native WinUI 3
+
+ImageResizer used the `WPF-UI` library (Lepo) for Fluent styling. These must be replaced with native WinUI 3 equivalents:
+
+| WPF-UI (Lepo) | WinUI 3 Native | Notes |
+|----------------|---------------|-------|
+| `<ui:FluentWindow>` | `<Window>` | Native window + `ExtendsContentIntoTitleBar` |
+| `<ui:Button>` | `<Button>` | Native button |
+| `<ui:NumberBox>` | `<NumberBox>` | Built into WinUI 3 |
+| `<ui:ProgressRing>` | `<ProgressRing>` | Built into WinUI 3 |
+| `<ui:SymbolIcon>` | `<SymbolIcon>` or `<FontIcon>` | Built into WinUI 3 |
+| `<ui:InfoBar>` | `<InfoBar>` | Built into WinUI 3 |
+| `<ui:TitleBar>` | Custom title bar via `SetTitleBar()` | Use `ExtendsContentIntoTitleBar` |
+| `<ui:ThemesDictionary>` | `<XamlControlsResources>` | In merged dictionaries |
+| `<ui:ControlsDictionary>` | Remove | Not needed — WinUI 3 has its own control styles |
+| `BasedOn="{StaticResource {x:Type ui:Button}}"` | `BasedOn="{StaticResource DefaultButtonStyle}"` | Named style keys |
+
+## Input Event Mapping
+
+| WPF Event | WinUI 3 Event | Notes |
+|-----------|--------------|-------|
+| `MouseLeftButtonDown` | `PointerPressed` | Check `IsLeftButtonPressed` on args |
+| `MouseLeftButtonUp` | `PointerReleased` | Check pointer properties |
+| `MouseRightButtonDown` | `RightTapped` | Or `PointerPressed` with right button check |
+| `MouseMove` | `PointerMoved` | Uses `PointerRoutedEventArgs` |
+| `MouseWheel` | `PointerWheelChanged` | Different event args |
+| `MouseEnter` | `PointerEntered` | |
+| `MouseLeave` | `PointerExited` | |
+| `MouseDoubleClick` | `DoubleTapped` | Different event args |
+| `KeyDown` | `KeyDown` | Same name, args type: `KeyRoutedEventArgs` |
+| `PreviewKeyDown` | No direct equivalent | Use `KeyDown` with handled pattern |
+
+## IValueConverter Signature Change
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `Convert(object value, Type targetType, object parameter, CultureInfo culture)` | `Convert(object value, Type targetType, object parameter, string language)` |
+| `ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)` | `ConvertBack(object value, Type targetType, object parameter, string language)` |
+
+Last parameter changes from `CultureInfo` to `string` (BCP-47 language tag). All converter classes must be updated.
+
+## Types That Moved to Different Hierarchies
+
+| WPF | WinUI 3 | Notes |
+|-----|---------|-------|
+| `System.Windows.Threading.Dispatcher` | `Microsoft.UI.Dispatching.DispatcherQueue` | Completely different API |
+| `System.Windows.Threading.DispatcherPriority` | `Microsoft.UI.Dispatching.DispatcherQueuePriority` | Only 3 levels: High/Normal/Low |
+| `System.Windows.Interop.HwndSource` | `WinRT.Interop.WindowNative` | For HWND interop |
+| `System.Windows.Interop.WindowInteropHelper` | `WinRT.Interop.WindowNative.GetWindowHandle()` | |
+| `System.Windows.SystemColors` | Resource keys via `ThemeResource` | No direct static class |
+| `System.Windows.SystemParameters` | Win32 API or `DisplayInformation` | No direct equivalent |
+
+## NuGet Package Migration
+
+| WPF | WinUI 3 | Notes |
+|-----|---------|-------|
+| Built into .NET (no NuGet needed) | `Microsoft.WindowsAppSDK` | Required |
+| `PresentationCore` / `PresentationFramework` | `Microsoft.WinUI` (transitive) | |
+| `Microsoft.Xaml.Behaviors.Wpf` | `Microsoft.Xaml.Behaviors.WinUI.Managed` | |
+| `WPF-UI` (Lepo) | **Remove** — use native WinUI 3 controls | |
+| `CommunityToolkit.Mvvm` | `CommunityToolkit.Mvvm` (same) | |
+| `Microsoft.Toolkit.Wpf.*` | `CommunityToolkit.WinUI.*` | |
+| (none) | `Microsoft.Windows.SDK.BuildTools` | Required |
+| (none) | `WinUIEx` | Optional, window helpers |
+| (none) | `CommunityToolkit.WinUI.Converters` | Optional |
+| (none) | `CommunityToolkit.WinUI.Extensions` | Optional |
+| (none) | `Microsoft.Web.WebView2` | If using WebView |
+
+## Project File Changes
+
+### WPF .csproj
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+  <PropertyGroup>
+    <OutputType>WinExe</OutputType>
+    <TargetFramework>net8.0-windows</TargetFramework>
+    <UseWPF>true</UseWPF>
+    <ApplicationManifest>ImageResizerUI.dev.manifest</ApplicationManifest>
+    <ApplicationIcon>Resources\ImageResizer.ico</ApplicationIcon>
+    <AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>

+</Project>
+```
+
+### WinUI 3 .csproj
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+  <PropertyGroup>
+    <OutputType>WinExe</OutputType>
+    <TargetFramework>net8.0-windows10.0.19041.0</TargetFramework>
+    <UseWinUI>true</UseWinUI>

+    <DefineConstants>DISABLE_XAML_GENERATED_MAIN,TRACE</DefineConstants>
+    <ProjectPriFileName>PowerToys.ModuleName.pri</ProjectPriFileName>
+  </PropertyGroup>
+</Project>
+```
+
+Key changes:
+- `UseWPF` → `UseWinUI`
+- TFM: `net8.0-windows` → `net8.0-windows10.0.19041.0`
+- Add `WindowsPackageType=None` for unpackaged desktop apps
+- Add `SelfContained=true` + `WindowsAppSDKSelfContained=true`
+- Add `DISABLE_XAML_GENERATED_MAIN` if using custom `Program.cs` entry point
+- Set `ProjectPriFileName` to match your module's assembly name
+- Move icon from `Resources/` to `Assets/<Module>/`
+
+### XAML ApplicationDefinition Setup
+
+WinUI 3 requires explicit `ApplicationDefinition` declaration:
+
+```xml
+<ItemGroup>
+  <Page Remove="ImageResizerXAML\App.xaml" />
+</ItemGroup>
+<ItemGroup>
+  <ApplicationDefinition Include="ImageResizerXAML\App.xaml" />
+</ItemGroup>
+```
+
+### CsWinRT Interop (for GPO and native references)
+
+If the module references native C++ projects (like `GPOWrapper`):
+
+```xml
+<PropertyGroup>
+  <CsWinRTIncludes>PowerToys.GPOWrapper</CsWinRTIncludes>
+  <CsWinRTGeneratedFilesDir>$(OutDir)</CsWinRTGeneratedFilesDir>
+</PropertyGroup>
+```
+
+Change `GPOWrapperProjection.csproj` reference to direct `GPOWrapper.vcxproj` reference.
+
+### InternalsVisibleTo Migration
+
+Move from code file to `.csproj`:
+
+```csharp
+// DELETE: Properties/InternalsVisibleTo.cs
+// [assembly: InternalsVisibleTo("ImageResizer.Test")]
+```
+
+```xml
+<!-- ADD to .csproj: -->
+<ItemGroup>
+  <InternalsVisibleTo Include="ImageResizer.Test" />
+</ItemGroup>
+```
+
+### Items to Remove from .csproj
+
+```xml
+<!-- DELETE: WPF resource embedding -->
+<EmbeddedResource Update="Properties\Resources.resx">...</EmbeddedResource>
+<Resource Include="Resources\ImageResizer.ico" />
+<Compile Update="Properties\Resources.Designer.cs">...</Compile>
+<FrameworkReference Include="Microsoft.WindowsDesktop.App.WPF" /> <!-- from CLI project -->
+```

+
+### Critical: CLI Dependency Pattern
+
+**Do NOT** create `ProjectReference` from Exe to WinExe. This causes phantom build artifacts (`.exe`, `.deps.json`, `.runtimeconfig.json`) in the root output directory.
+
+```
+WRONG:  ImageResizerCLI (Exe) → ImageResizerUI (WinExe)    ← phantom artifacts
+CORRECT: ImageResizerCLI (Exe) → ImageResizerCommon (Library)
+         ImageResizerUI (WinExe) → ImageResizerCommon (Library)
+```
+
+Follow the `FancyZonesCLI` → `FancyZonesEditorCommon` pattern.
+
+### Files to Delete
+
+| File | Reason |
+|------|--------|
+| `Properties/Resources.resx` | Replaced by `Strings/en-us/Resources.resw` |
+| `Properties/Resources.Designer.cs` | Auto-generated; no longer needed |
+| `Properties/InternalsVisibleTo.cs` | Moved to `.csproj` `<InternalsVisibleTo>` |
+| `Helpers/Observable.cs` | Replaced by `CommunityToolkit.Mvvm.ObservableObject` |
+| `Helpers/RelayCommand.cs` | Replaced by `CommunityToolkit.Mvvm.Input` |
+| `Resources/*.ico` / `Resources/*.png` | Moved to `Assets/<Module>/` |
+| WPF `.dev.manifest` / `.prod.manifest` | Replaced by single `app.manifest` |
+| WPF-specific converters | Replaced by WinUI 3 converters with `string language` |
+
+---
+
+## MVVM Migration: Custom → CommunityToolkit.Mvvm Source Generators
+
+### Observable Base Class → ObservableObject + [ObservableProperty]
+
+**Before (custom Observable):**
+```csharp
+public class ResizeSize : Observable
+{
+    private int _id;
+    public int Id { get => _id; set => Set(ref _id, value); }
+
+    private ResizeFit _fit;
+    public ResizeFit Fit
+    {
+        get => _fit;
+        set
+        {
+            Set(ref _fit, value);
+            UpdateShowHeight();
+        }
+    }
+
+    private bool _showHeight = true;
+    public bool ShowHeight { get => _showHeight; set => Set(ref _showHeight, value); }
+    private void UpdateShowHeight() { ShowHeight = Fit == ResizeFit.Stretch || Unit != ResizeUnit.Percent; }
+}
+```
+
+**After (CommunityToolkit.Mvvm source generators):**
+```csharp
+public partial class ResizeSize : ObservableObject  // MUST be partial
+{
+    [ObservableProperty]
+    [JsonPropertyName("Id")]
+    private int _id;
+
+    [ObservableProperty]
+    [NotifyPropertyChangedFor(nameof(ShowHeight))]  // Replaces manual UpdateShowHeight()
+    private ResizeFit _fit;
+
+    // Computed property — no backing field, no manual update method
+    public bool ShowHeight => Fit == ResizeFit.Stretch || Unit != ResizeUnit.Percent;
+}
+```
+
+Key changes:
+- Class must be `partial` for source generators
+- `Observable` → `ObservableObject` (from CommunityToolkit.Mvvm)
+- Manual `Set(ref _field, value)` → `[ObservableProperty]` attribute
+- `PropertyChanged` dependencies → `[NotifyPropertyChangedFor(nameof(...))]`
+- Computed properties with manual `UpdateXxx()` → direct expression body
+
+### Custom Name Setter with Transform
+
+For properties that transform the value before storing:
+
+```csharp
+// Cannot use [ObservableProperty] because of value transformation
+private string _name;
+public string Name
+{
+    get => _name;
+    set => SetProperty(ref _name, ReplaceTokens(value));  // SetProperty from ObservableObject
+}
+```
+
+### RelayCommand → [RelayCommand] Source Generator
+
+```csharp
+// DELETE: Helpers/RelayCommand.cs (custom ICommand)
+
+// Before
+public ICommand ResizeCommand { get; } = new RelayCommand(Execute);
+
+// After
+[RelayCommand]
+private void Resize() { /* ... */ }
+// Source generator creates ResizeCommand property automatically
+```
+
+---
+
+## Resource String Migration (.resx → .resw)
+
+### ResourceLoaderInstance Helper
+
+```csharp
+internal static class ResourceLoaderInstance
+{
+    internal static ResourceLoader ResourceLoader { get; private set; }
+
+    static ResourceLoaderInstance()
+    {
+        ResourceLoader = new ResourceLoader("PowerToys.ImageResizer.pri");
+    }
+}
+```
+
+**Note**: Use the single-argument `ResourceLoader` constructor. The two-argument version (`ResourceLoader("file.pri", "path/Resources")`) may fail if the resource map path doesn't match the actual PRI structure.
+
+### Usage
+
+```csharp
+// WPF
+using ImageResizer.Properties;
+string text = Resources.MyStringKey;
+
+// WinUI 3
+string text = ResourceLoaderInstance.ResourceLoader.GetString("MyStringKey");
+```
+
+### Lazy Initialization for Resource-Dependent Statics
+
+`ResourceLoader` is not available at class-load time in all contexts (CLI mode, test harness). Use lazy initialization:
+
+**Before (crashes at class load):**
+```csharp
+private static readonly CompositeFormat _format =
+    CompositeFormat.Parse(Resources.Error_Format);
+
+private static readonly Dictionary<string, string> _tokens = new()
+{
+    ["$small$"] = Resources.Small,
+    ["$medium$"] = Resources.Medium,
+};
+```
+
+**After (lazy, safe):**
+```csharp
+private static CompositeFormat _format;
+private static CompositeFormat Format => _format ??=
+    CompositeFormat.Parse(ResourceLoaderInstance.ResourceLoader.GetString("Error_Format"));
+
+private static readonly Lazy<Dictionary<string, string>> _tokens = new(() =>
+    new Dictionary<string, string>
+    {
+        ["$small$"] = ResourceLoaderInstance.ResourceLoader.GetString("Small"),
+        ["$medium$"] = ResourceLoaderInstance.ResourceLoader.GetString("Medium"),
+    });
+// Usage: _tokens.Value.TryGetValue(...)
+```
+
+### XAML: x:Static → x:Uid
+
+```xml
+<!-- WPF -->
+<Button Content="{x:Static p:Resources.Cancel}" />
+<!-- WinUI 3 -->
+<Button x:Uid="Cancel" />
+```
+
+In `.resw`, use property-suffixed keys: `Cancel.Content`, `Header.Text`, etc.
+
+---
+
+## CLI Options Migration
+
+`System.CommandLine.Option<T>` constructor signature changed:
+
+```csharp
+// WPF era — string[] aliases
+public DestinationOption()
+    : base(_aliases, Properties.Resources.CLI_Option_Destination)
+
+// WinUI 3 — single string name
+public DestinationOption()
+    : base(_aliases[0], ResourceLoaderInstance.ResourceLoader.GetString("CLI_Option_Destination"))
+```
+
+---
+
+## Installer Updates
+
+### WiX Changes
+
+#### 1. Remove Satellite Assembly References
+
+Remove from `installer/PowerToysSetupVNext/Resources.wxs`:
+- `<Component>` entries for `<Module>.resources.dll`
+- `<RemoveFolder>` entries for locale directories
+- Module from `WinUI3AppsInstallFolder` `ParentDirectory` loop
+
+#### 2. Update File Component Generation
+
+Run `generateAllFileComponents.ps1` after migration. For Exe→WinExe dependency issues, add cleanup logic:
+
+```powershell
+# Strip phantom ImageResizer files from BaseApplications.wxs
+$content = $content -replace 'PowerToys\.ImageResizer\.exe', ''
+$content = $content -replace 'PowerToys\.ImageResizer\.deps\.json', ''
+$content = $content -replace 'PowerToys\.ImageResizer\.runtimeconfig\.json', ''
+```
+
+#### 3. Output Directory
+
+WinUI 3 modules output to `WinUI3Apps/`:
+```xml
+<OutputPath>..\..\..\..\$(Platform)\$(Configuration)\WinUI3Apps\</OutputPath>
+```
+
+### ESRP Signing
+
+Update `.pipelines/ESRPSigning_core.json` — all module binaries must use `WinUI3Apps\\` paths:
+
+```json
+{
+    "FileList": [
+        "WinUI3Apps\\PowerToys.ImageResizer.exe",
+        "WinUI3Apps\\PowerToys.ImageResizerExt.dll",
+        "WinUI3Apps\\PowerToys.ImageResizerContextMenu.dll"
+    ]
+}
+```
+
+---
+
+## Build Pipeline Fixes
+
+### $(SolutionDir) → $(MSBuildThisFileDirectory)
+
+`$(SolutionDir)` is empty when building individual projects outside the solution. Replace with relative paths from the project file:
+
+```xml
+<!-- Before (breaks on standalone project build) -->
+<Exec Command="powershell $(SolutionDir)tools\build\convert-resx-to-rc.ps1" />
+
+<!-- After (works always) -->
+<Exec Command="powershell $(MSBuildThisFileDirectory)..\..\..\..\tools\build\convert-resx-to-rc.ps1" />
+```
+
+### MSIX Packaging: PreBuild → PostBuild
+
+MSIX packaging must happen AFTER the build (artifacts not ready at PreBuild):
+
+```xml
+<!-- Before -->
+<PreBuildEvent>MakeAppx.exe pack /d . /p "$(OutDir)Package.msix" /o</PreBuildEvent>
+
+<!-- After -->
+<PostBuildEvent>
+  if exist "$(OutDir)Package.msix" del "$(OutDir)Package.msix"
+  MakeAppx.exe pack /d "$(MSBuildThisFileDirectory)." /p "$(OutDir)Package.msix" /o
+</PostBuildEvent>
+```
+
+### RC File Icon Path Escaping
+
+Windows Resource Compiler requires double-backslash paths:
+
+```c
+// Before (breaks)
+IDI_ICON1 ICON "..\\ui\Assets\ImageResizer\ImageResizer.ico"
+// After
+IDI_ICON1 ICON "..\\ui\\Assets\\ImageResizer\\ImageResizer.ico"
+```
+
+### BOM/Encoding Normalization
+
+Migration may strip UTF-8 BOM from C# files (`// Copyright` → `// Copyright`). This is cosmetic and safe, but be aware it will show as changes in diff.
+
+---
+
+## Test Adaptation
+
+### Tests Requiring WPF Runtime
+
+If tests still need WPF types (e.g., comparing old vs new output), temporarily add:
+```xml
+<UseWPF>true</UseWPF>
+```
+Remove this after fully migrating all test code to WinRT APIs.
+
+### Tests Using ResourceLoader
+
+Unit tests cannot easily initialize WinUI 3 `ResourceLoader`. Options:
+- Hardcode expected strings in tests: `"Value must be between '{0}' and '{1}'."`
+- Delete tests that only verify resource string lookup
+- Avoid creating `App` instances in test harness (WinUI App cannot be instantiated in tests)
+
+### Async Test Methods
+
+All imaging tests become async:
+```csharp
+// Before
+[TestMethod]
+public void ResizesImage() { ... }
+
+// After
+[TestMethod]
+public async Task ResizesImageAsync() { ... }
+```
+
+### uint Assertions
+
+```csharp
+// Before
+Assert.AreEqual(96, image.Frames[0].PixelWidth);
+// After
+Assert.AreEqual(96u, decoder.PixelWidth);
+```
+
+### Pixel Data Access in Tests
+
+```csharp
+// Before (WPF)
+public static Color GetFirstPixel(this BitmapSource source)
+{
+    var pixel = new byte[4];
+    new FormatConvertedBitmap(
+        new CroppedBitmap(source, new Int32Rect(0, 0, 1, 1)),
+        PixelFormats.Bgra32, null, 0).CopyPixels(pixel, 4, 0);
+    return Color.FromArgb(pixel[3], pixel[2], pixel[1], pixel[0]);
+}
+
+// After (WinRT)
+public static async Task<(byte R, byte G, byte B, byte A)> GetFirstPixelAsync(
+    this BitmapDecoder decoder)
+{
+    using var bitmap = await decoder.GetSoftwareBitmapAsync(
+        BitmapPixelFormat.Bgra8, BitmapAlphaMode.Premultiplied);
+    var buffer = new Windows.Storage.Streams.Buffer(
+        (uint)(bitmap.PixelWidth * bitmap.PixelHeight * 4));
+    bitmap.CopyToBuffer(buffer);
+    using var reader = DataReader.FromBuffer(buffer);
+    byte b = reader.ReadByte(), g = reader.ReadByte(),
+         r = reader.ReadByte(), a = reader.ReadByte();
+    return (r, g, b, a);
+}
+```
+
+### Metadata Assertions
+
+```csharp
+// Before
+Assert.AreEqual("Test", ((BitmapMetadata)image.Frames[0].Metadata).Comment);
+
+// After
+var props = await decoder.BitmapProperties.GetPropertiesAsync(
+    new[] { "System.Photo.DateTaken" });
+Assert.IsTrue(props.ContainsKey("System.Photo.DateTaken"),
+    "Metadata should be preserved during transcode");
+```
+
+### AllowUnsafeBlocks for SoftwareBitmap Tests
+
+If tests access pixel data via `IMemoryBufferByteAccess`, add:
+```xml
+<AllowUnsafeBlocks>true</AllowUnsafeBlocks>
+```
+
+---
+
+## Settings JSON Backward Compatibility
+
+- Settings are stored in `%LOCALAPPDATA%\Microsoft\PowerToys\<ModuleName>\`
+- Schema must remain backward-compatible across upgrades
+- Add new fields with defaults; never remove or rename existing fields
+- Create custom enums matching WPF enum integer values for deserialization (e.g., `ImagingEnums.cs`)
+- See: `src/settings-ui/Settings.UI.Library/`
+
+## IPC Contract
+
+If the module communicates with the runner or settings UI:
+1. Update BOTH sides of the IPC contract
+2. Test settings changes are received by the module
+3. Test module state changes are reflected in settings UI
+4. Reference: `doc/devdocs/core/settings/runner-ipc.md`
+
+---
+
+## Checklist for PowerToys Module Migration
+
+### Project & Dependencies

+# Threading and Window Management Migration
+
+Based on patterns from the ImageResizer migration.
+
+## Dispatcher → DispatcherQueue
+
+### API Mapping
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `Dispatcher.Invoke(Action)` | `DispatcherQueue.TryEnqueue(Action)` |
+| `Dispatcher.BeginInvoke(Action)` | `DispatcherQueue.TryEnqueue(Action)` |
+| `Dispatcher.Invoke(DispatcherPriority, Action)` | `DispatcherQueue.TryEnqueue(DispatcherQueuePriority, Action)` |
+| `Dispatcher.CheckAccess()` | `DispatcherQueue.HasThreadAccess` |
+| `Dispatcher.VerifyAccess()` | Check `DispatcherQueue.HasThreadAccess` (no exception-throwing method) |
+
+### Priority Mapping
+
+WinUI 3 has only 3 levels: `High`, `Normal`, `Low`.
+
+| WPF `DispatcherPriority` | WinUI 3 `DispatcherQueuePriority` |
+|-------------------------|----------------------------------|
+| `Send` | `High` |
+| `Normal` / `Input` / `Loaded` / `Render` / `DataBind` | `Normal` |
+| `Background` / `ContextIdle` / `ApplicationIdle` / `SystemIdle` | `Low` |
+
+### Pattern: Global DispatcherQueue Access (from ImageResizer)
+
+WPF provided `Application.Current.Dispatcher` globally. WinUI 3 requires explicit storage:
+
+```csharp
+// Store DispatcherQueue at app startup
+private static DispatcherQueue _uiDispatcherQueue;
+
+public static void InitializeDispatcher()
+{
+    _uiDispatcherQueue = DispatcherQueue.GetForCurrentThread();
+}
+```
+
+Usage with thread-check pattern (from `Settings.Reload()`):
+```csharp
+var currentDispatcher = DispatcherQueue.GetForCurrentThread();
+if (currentDispatcher != null)
+{
+    // Already on UI thread
+    ReloadCore(jsonSettings);
+}
+else if (_uiDispatcherQueue != null)
+{
+    // Dispatch to UI thread
+    _uiDispatcherQueue.TryEnqueue(() => ReloadCore(jsonSettings));
+}
+else
+{
+    // Fallback (e.g., CLI mode, no UI)
+    ReloadCore(jsonSettings);
+}
+```
+
+### Pattern: DispatcherQueue in ViewModels (from ProgressViewModel)
+
+```csharp
+public class ProgressViewModel
+{
+    private readonly DispatcherQueue _dispatcherQueue;
+
+    public ProgressViewModel()
+    {
+        _dispatcherQueue = DispatcherQueue.GetForCurrentThread();
+    }
+
+    private void OnProgressChanged(double progress)
+    {
+        _dispatcherQueue.TryEnqueue(() =>
+        {
+            Progress = progress;
+            // other UI updates...
+        });
+    }
+}
+```
+
+### Pattern: Async Dispatch (await)
+
+```csharp
+// WPF
+await this.Dispatcher.InvokeAsync(() => { /* UI work */ });
+
+// WinUI 3 (using TaskCompletionSource)
+var tcs = new TaskCompletionSource();
+this.DispatcherQueue.TryEnqueue(() =>
+{
+    try { /* UI work */ tcs.SetResult(); }
+    catch (Exception ex) { tcs.SetException(ex); }
+});
+await tcs.Task;
+```
+
+### C++/WinRT Threading
+
+| Old API | New API |
+|---------|---------|
+| `winrt::resume_foreground(CoreDispatcher)` | `wil::resume_foreground(DispatcherQueue)` |
+| `CoreDispatcher.RunAsync()` | `DispatcherQueue.TryEnqueue()` |
+
+Add `Microsoft.Windows.ImplementationLibrary` NuGet for `wil::resume_foreground`.
+
+---
+
+## Window Management
+
+### WPF Window vs WinUI 3 Window
+
+| Feature | WPF `Window` | WinUI 3 `Window` |
+|---------|-------------|------------------|
+| Base class | `ContentControl` → `DependencyObject` | **NOT** a control, NOT a `DependencyObject` |
+| `Resources` property | Yes | No — use root container's `Resources` |
+| `DataContext` property | Yes | No — use root `Page`/`UserControl` |
+| `VisualStateManager` | Yes | No — use inside child controls |
+| `Load`/`Unload` events | Yes | No |
+| `SizeToContent` | Yes (`Height`/`Width`/`WidthAndHeight`) | No — must implement manually |
+| `WindowState` (min/max/normal) | Yes | No — use `AppWindow.Presenter` |
+| `WindowStyle` | Yes | No — use `AppWindow` title bar APIs |
+| `ResizeMode` | Yes | No — use `AppWindow.Presenter` |
+| `WindowStartupLocation` | Yes | No — calculate manually |
+| `Icon` | `Window.Icon` | `AppWindow.SetIcon()` |
+| `Title` | `Window.Title` | `AppWindow.Title` (or `Window.Title`) |
+| Size (Width/Height) | Yes | No — use `AppWindow.Resize()` |
+| Position (Left/Top) | Yes | No — use `AppWindow.Move()` |
+| `IsDefault`/`IsCancel` on buttons | Yes | No — handle Enter/Escape in code-behind |
+
+### Getting AppWindow from Window
+
+```csharp
+using Microsoft.UI;
+using Microsoft.UI.Windowing;
+using WinRT.Interop;
+
+IntPtr hwnd = WindowNative.GetWindowHandle(window);
+WindowId windowId = Win32Interop.GetWindowIdFromWindow(hwnd);
+AppWindow appWindow = AppWindow.GetFromWindowId(windowId);
+```
+
+### Pattern: SizeToContent Replacement (from ImageResizer)
+
+WinUI 3 has no `SizeToContent`. ImageResizer implemented a manual equivalent:
+
+```csharp
+private void SizeToContent()
+{
+    if (Content is not FrameworkElement content)
+        return;
+
+    // Measure desired content size
+    content.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
+    var desiredHeight = content.DesiredSize.Height + WindowChromeHeight + Padding;
+
+    // Account for DPI scaling
+    var scaleFactor = Content.XamlRoot.RasterizationScale;
+    var pixelHeight = (int)(desiredHeight * scaleFactor);
+    var pixelWidth = (int)(WindowWidth * scaleFactor);
+
+    // Resize via AppWindow
+    var hwnd = WindowNative.GetWindowHandle(this);
+    var windowId = Win32Interop.GetWindowIdFromWindow(hwnd);
+    var appWindow = AppWindow.GetFromWindowId(windowId);
+    appWindow.Resize(new Windows.Graphics.SizeInt32(pixelWidth, pixelHeight));
+}
+```
+
+**Key details:**
+- `WindowChromeHeight` ≈ 32px for the title bar
+- Must multiply by `RasterizationScale` for DPI-aware sizing
+- Call `SizeToContent()` after page navigation or content changes
+- Unsubscribe previous event handlers before subscribing new ones to avoid memory leaks
+
+### Window Positioning (Center Screen)
+
+```csharp
+var displayArea = DisplayArea.GetFromWindowId(windowId, DisplayAreaFallback.Nearest);
+var centerX = (displayArea.WorkArea.Width - appWindow.Size.Width) / 2;
+var centerY = (displayArea.WorkArea.Height - appWindow.Size.Height) / 2;
+appWindow.Move(new Windows.Graphics.PointInt32(centerX, centerY));
+```
+
+### Window State (Minimize/Maximize)
+
+```csharp
+(appWindow.Presenter as OverlappedPresenter)?.Maximize();
+(appWindow.Presenter as OverlappedPresenter)?.Minimize();
+(appWindow.Presenter as OverlappedPresenter)?.Restore();
+```
+
+### Title Bar Customization
+
+```csharp
+// Extend content into title bar
+this.ExtendsContentIntoTitleBar = true;
+this.SetTitleBar(AppTitleBar); // AppTitleBar is a XAML element
+
+// Or via AppWindow API
+if (AppWindowTitleBar.IsCustomizationSupported())
+{
+    var titleBar = appWindow.TitleBar;
+    titleBar.ExtendsContentIntoTitleBar = true;
+    titleBar.ButtonBackgroundColor = Colors.Transparent;
+}
+```
+
+### Tracking the Main Window
+
+```csharp
+public partial class App : Application
+{
+    public static Window MainWindow { get; private set; }
+
+    protected override void OnLaunched(LaunchActivatedEventArgs args)
+    {
+        MainWindow = new MainWindow();
+        MainWindow.Activate();
+    }
+}
+```
+
+### ContentDialog Requires XamlRoot
+
+```csharp
+var dialog = new ContentDialog
+{
+    Title = "Confirm",
+    Content = "Are you sure?",
+    PrimaryButtonText = "Yes",
+    CloseButtonText = "No",
+    XamlRoot = this.Content.XamlRoot  // REQUIRED
+};
+var result = await dialog.ShowAsync();
+```
+
+### File Pickers Require HWND
+
+```csharp
+var picker = new FileOpenPicker();
+picker.FileTypeFilter.Add(".jpg");
+
+// REQUIRED for desktop apps
+var hwnd = WindowNative.GetWindowHandle(App.MainWindow);
+WinRT.Interop.InitializeWithWindow.Initialize(picker, hwnd);
+
+var file = await picker.PickSingleFileAsync();
+```
+
+### Window Close Handling
+
+```csharp
+// WPF
+protected override void OnClosing(CancelEventArgs e) { e.Cancel = true; this.Hide(); }
+
+// WinUI 3
+this.AppWindow.Closing += (s, e) => { e.Cancel = true; this.AppWindow.Hide(); };
+```
+
+---
+
+## Custom Entry Point (DISABLE_XAML_GENERATED_MAIN)
+
+ImageResizer uses a custom `Program.cs` entry point instead of the WinUI 3 auto-generated `Main`. This is needed for:
+- CLI mode (process files without showing UI)
+- Custom initialization before the WinUI 3 App starts
+- Single-instance enforcement
+
+### Setup
+
+In `.csproj`:
+```xml
+<DefineConstants>DISABLE_XAML_GENERATED_MAIN,TRACE</DefineConstants>
+```
+
+Create `Program.cs`:
+```csharp
+public static class Program
+{
+    [STAThread]
+    public static int Main(string[] args)
+    {
+        if (args.Length > 0)
+        {
+            // CLI mode — no UI
+            return RunCli(args);
+        }
+
+        // GUI mode
+        WinRT.ComWrappersSupport.InitializeComWrappers();
+        Application.Start((p) =>
+        {
+            var context = new DispatcherQueueSynchronizationContext(
+                DispatcherQueue.GetForCurrentThread());
+            SynchronizationContext.SetSynchronizationContext(context);
+            _ = new App();
+        });
+        return 0;
+    }
+}
+```
+
+### WPF App Constructor Removal
+
+WPF modules often created `new App()` to initialize the WPF `Application` and get `Application.Current.Dispatcher`. This is no longer needed — the WinUI 3 `Application.Start()` handles this.
+
+```csharp
+// DELETE (WPF pattern):
+_imageResizerApp = new App();
+// REPLACE with: Store DispatcherQueue explicitly (see Global DispatcherQueue Access above)
+```

+# XAML Migration Guide
+
+Detailed reference for migrating XAML from WPF to WinUI 3, based on the ImageResizer migration.
+
+## XML Namespace Declaration Changes
+
+### Before (WPF)
+
+```xml
+<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+        xmlns:local="clr-namespace:MyApp"
+        xmlns:m="clr-namespace:ImageResizer.Models"
+        xmlns:p="clr-namespace:ImageResizer.Properties"
+        xmlns:sys="clr-namespace:System;assembly=mscorlib"
+        xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml"
+        x:Class="MyApp.MainWindow">
+```
+
+### After (WinUI 3)
+
+```xml
+<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+        xmlns:local="using:MyApp"
+        xmlns:m="using:ImageResizer.Models"
+        xmlns:converters="using:ImageResizer.Converters"
+        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
+        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
+        x:Class="MyApp.MainWindow">
+```
+
+### Key Changes
+
+| WPF Syntax | WinUI 3 Syntax | Notes |
+|------------|---------------|-------|
+| `clr-namespace:Foo` | `using:Foo` | CLR namespace mapping |
+| `clr-namespace:Foo;assembly=Bar` | `using:Foo` | Assembly qualification not needed |
+| `xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml"` | **Remove entirely** | WPF-UI namespace no longer needed |
+| `xmlns:p="clr-namespace:...Properties"` | **Remove** | No more `.resx` string bindings |
+| `sys:String` (from mscorlib) | `x:String` | XAML intrinsic types |
+| `sys:Int32` | `x:Int32` | XAML intrinsic types |
+| `sys:Boolean` | `x:Boolean` | XAML intrinsic types |
+| `sys:Double` | `x:Double` | XAML intrinsic types |
+
+## Unsupported Markup Extensions
+
+| WPF Markup Extension | WinUI 3 Alternative |
+|----------------------|---------------------|
+| `{DynamicResource Key}` | `{ThemeResource Key}` (theme-reactive) or `{StaticResource Key}` |
+| `{x:Static Type.Member}` | `{x:Bind}` to a static property, or code-behind |
+| `{x:Type local:MyType}` | Not supported; use code-behind |
+| `{x:Array}` | Not supported; create collections in code-behind |
+| `{x:Code}` | Not supported |
+
+### DynamicResource → ThemeResource
+
+```xml
+<!-- WPF -->
+<TextBlock Foreground="{DynamicResource MyBrush}" />
+
+<!-- WinUI 3 -->
+<TextBlock Foreground="{ThemeResource MyBrush}" />
+```
+
+`ThemeResource` automatically updates when the app theme changes (Light/Dark/HighContrast). For truly dynamic non-theme resources, set values in code-behind or use data binding.
+
+### x:Static Resource Strings → x:Uid
+
+This is the most pervasive XAML change. WPF used `{x:Static}` to bind to strongly-typed `.resx` resource strings. WinUI 3 uses `x:Uid` with `.resw` files.
+
+**WPF:**
+```xml
+<Button Content="{x:Static p:Resources.Cancel}" />
+<TextBlock Text="{x:Static p:Resources.Input_Header}" />
+```
+
+**WinUI 3:**
+```xml
+<Button x:Uid="Cancel" />
+<TextBlock x:Uid="Input_Header" />
+```
+
+In `Strings/en-us/Resources.resw`:
+```xml
+<data name="Cancel.Content" xml:space="preserve">
+    <value>Cancel</value>
+</data>
+<data name="Input_Header.Text" xml:space="preserve">
+    <value>Select a size</value>
+</data>
+```
+
+The `x:Uid` suffix (`.Content`, `.Text`, `.Header`, `.PlaceholderText`, etc.) matches the target property name.
+
+### DataType with x:Type → Remove
+
+**WPF:**
+```xml
+<DataTemplate DataType="{x:Type m:ResizeSize}">
+```
+
+**WinUI 3:**
+```xml
+<DataTemplate x:DataType="m:ResizeSize">
+```
+
+## WPF-UI (Lepo) Controls Removal
+
+If the module uses the `WPF-UI` library, replace all Lepo controls with native WinUI 3 equivalents.
+
+### Window
+
+```xml
+<!-- WPF (WPF-UI) -->
+<ui:FluentWindow
+    ExtendsContentIntoTitleBar="True"
+    WindowStartupLocation="CenterScreen">
+    <ui:TitleBar Title="Image Resizer" />
+    ...
+</ui:FluentWindow>
+
+<!-- WinUI 3 (native) -->
+<Window>
+    <!-- Title bar managed via code-behind: this.ExtendsContentIntoTitleBar = true; -->
+    ...
+</Window>
+```
+
+### App.xaml Resources

+<Button Style="{StaticResource AccentButtonStyle}" Content="OK" />
+<Button Content="Cancel" />
+<!-- Handle Enter/Escape keys in code-behind if needed -->
+```
+
+## Style and Template Changes
+
+### Triggers → VisualStateManager
+
+WPF `Triggers`, `DataTriggers`, and `EventTriggers` are not supported.
+
+**WPF:**
+```xml
+<Style TargetType="Button">
+    <Style.Triggers>
+        <Trigger Property="IsMouseOver" Value="True">
+            <Setter Property="Background" Value="LightBlue"/>
+        </Trigger>
+        <DataTrigger Binding="{Binding IsEnabled}" Value="False">
+            <Setter Property="Opacity" Value="0.5"/>
+        </DataTrigger>
+    </Style.Triggers>
+</Style>
+```
+
+**WinUI 3:**
+```xml
+<Style TargetType="Button">
+    <Setter Property="Template">
+        <Setter.Value>
+            <ControlTemplate TargetType="Button">
+                <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
+                    <VisualStateManager.VisualStateGroups>
+                        <VisualStateGroup x:Name="CommonStates">
+                            <VisualState x:Name="PointerOver">
+                                <VisualState.Setters>
+                                    <Setter Target="RootGrid.Background" Value="LightBlue"/>
+                                </VisualState.Setters>
+                            </VisualState>
+                        </VisualStateGroup>
+                    </VisualStateManager.VisualStateGroups>
+                    <ContentPresenter />
+                </Grid>
+            </ControlTemplate>
+        </Setter.Value>
+    </Setter>
+</Style>
+```
+
+### No Binding in Setter.Value
+
+```xml
+<!-- WPF (works) -->
+<Setter Property="Foreground" Value="{Binding TextColor}"/>
+
+<!-- WinUI 3 (does NOT work — use StaticResource) -->
+<Setter Property="Foreground" Value="{StaticResource TextColorBrush}"/>
+```
+
+### Visual State Name Changes
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `MouseOver` | `PointerOver` |
+| `Disabled` | `Disabled` |
+| `Pressed` | `Pressed` |
+
+## Resource Dictionary Changes
+
+### Window.Resources → Grid.Resources
+
+WinUI 3 `Window` is NOT a `DependencyObject` — no `Window.Resources`, `DataContext`, or `VisualStateManager`.
+
+```xml
+<!-- WPF -->
+<Window>
+    <Window.Resources>
+        <SolidColorBrush x:Key="MyBrush" Color="Red"/>
+    </Window.Resources>
+    <Grid>...</Grid>
+</Window>
+
+<!-- WinUI 3 -->
+<Window>
+    <Grid>
+        <Grid.Resources>
+            <SolidColorBrush x:Key="MyBrush" Color="Red"/>
+        </Grid.Resources>
+        ...
+    </Grid>
+</Window>
+```
+
+### Theme Dictionaries
+
+```xml
+<ResourceDictionary>
+    <ResourceDictionary.ThemeDictionaries>
+        <ResourceDictionary x:Key="Light">
+            <SolidColorBrush x:Key="MyBrush" Color="#FF000000"/>
+        </ResourceDictionary>
+        <ResourceDictionary x:Key="Dark">
+            <SolidColorBrush x:Key="MyBrush" Color="#FFFFFFFF"/>
+        </ResourceDictionary>
+        <ResourceDictionary x:Key="HighContrast">
+            <SolidColorBrush x:Key="MyBrush" Color="{ThemeResource SystemColorWindowTextColor}"/>
+        </ResourceDictionary>
+    </ResourceDictionary.ThemeDictionaries>
+</ResourceDictionary>
+```
+
+## URI Scheme Changes
+
+| WPF | WinUI 3 |
+|-----|---------|
+| `pack://application:,,,/MyAssembly;component/image.png` | `ms-appx:///Assets/image.png` |
+| `pack://application:,,,/image.png` | `ms-appx:///image.png` |
+| Relative path `../image.png` | `ms-appx:///image.png` |
+
+Assets directory convention: `Resources/` → `Assets/<Module>/`
+
+## Data Binding Changes
+
+### {Binding} vs {x:Bind}
+
+Both are available. Prefer `{x:Bind}` for compile-time safety and performance.
+
+| Feature | `{Binding}` | `{x:Bind}` |
+|---------|------------|------------|
+| Default mode | `OneWay` | **`OneTime`** (explicit `Mode=OneWay` required!) |
+| Context | `DataContext` | Code-behind class |
+| Resolution | Runtime | Compile-time |
+| Performance | Reflection-based | Compiled |
+| Function binding | No | Yes |
+
+### WPF-Specific Binding Features to Remove
+
+```xml
+<!-- These WPF-only features must be removed or rewritten -->
+<TextBox Text="{Binding Value, UpdateSourceTrigger=PropertyChanged}" />
+<!-- WinUI 3: UpdateSourceTrigger not needed; TextBox uses PropertyChanged by default -->
+<TextBox Text="{x:Bind ViewModel.Value, Mode=TwoWay}" />
+
+{Binding RelativeSource={RelativeSource Self}, ...}
+<!-- WinUI 3: Use x:Bind which binds to the page itself, or use ElementName -->
+
+<ItemsControl ItemsSource="{Binding}" />
+<!-- WinUI 3: Must specify explicit path -->
+<ItemsControl ItemsSource="{x:Bind ViewModel.Items}" />
+```
+
+## WPF-Only Window Properties to Remove
+
+These properties exist on WPF `Window` but not WinUI 3:
+
+```xml
+<!-- Remove from XAML — handle in code-behind via AppWindow API -->
+SizeToContent="Height"
+WindowStartupLocation="CenterScreen"
+ResizeMode="NoResize"
+ExtendsContentIntoTitleBar="True"  <!-- Set in code-behind -->
+```
+
+## XAML Control Property Changes
+
+| WPF Property | WinUI 3 Property | Notes |
+|-------------|-----------------|-------|
+| `Focusable` | `IsTabStop` | Different name |
+| `SnapsToDevicePixels` | Not available | WinUI handles pixel snapping internally |
+| `UseLayoutRounding` | `UseLayoutRounding` | Same |
+| `IsHitTestVisible` | `IsHitTestVisible` | Same |
+| `TextBox.VerticalScrollBarVisibility` | `ScrollViewer.VerticalScrollBarVisibility` (attached) | Attached property |
+
+## XAML Formatting (XamlStyler)
+
+After migration, run XamlStyler to normalize formatting:
+- Alphabetize xmlns declarations and element attributes
+- Add UTF-8 BOM to all XAML files
+- Normalize comment spacing: `<!-- text -->` → `<!--  text  -->`
+

+
+            Automated update of the Monaco Editor dependency.
+
+            **Previous version:** ${{ steps.current_version.outputs.version }}
+            **New version:** ${{ steps.update.outputs.new_version }}
+
+            ## Changes
+
+            - Updated `src/Monaco/monacoSRC/min/` with the new Monaco Editor release
+            - Regenerated `src/Monaco/monaco_languages.json`
+
+            ## Validation
+
+            The following automated checks passed:
+            - ✅ `loader.js` contains valid version header
+            - ✅ `monaco_languages.json` is valid JSON with expected structure
+            - ✅ All expected built-in languages are present
+            - ✅ All PowerToys custom languages (reg, gitignore, srt) are present
+            - ✅ All custom language extensions are registered
+            - ✅ Monaco directory structure is intact
+
+            ## Manual Verification
+
+            Before merging, please verify:
+            - [ ] File Explorer Dev File Preview works correctly
+            - [ ] Peek module previews code files properly
+            - [ ] Registry Preview module functions normally
