## Summary
Fixes all 13 **WMC1506** XAML compiler warnings ("OneWay bindings
require at least one of their steps to support raising notifications
when their value changes") by changing \Mode=OneWay\ to \Mode=OneTime\
on \x:Bind\ expressions bound to non-observable properties.
## Details
**Root cause:** \PasteFormat\ (plain sealed class) and \ClipboardItem\
(plain class) do not implement \INotifyPropertyChanged\. Using
\Mode=OneWay\ on their properties creates subscriptions that will never
fire, generating WMC1506 warnings.
**Fix:** Changed to \Mode=OneTime\ which is semantically correct — these
properties are set once and never change after construction.
**Files changed:**
- \ClipboardHistoryItemPreviewControl.xaml\ — 2 bindings (\Header\,
\Timestamp\)
- \MainPage.xaml\ — 11 bindings across \PasteFormat\ and \ClipboardItem\
DataTemplates
**Note on ClipboardHistoryItemPreviewControl:** Its computed properties
(\Header\, \Timestamp\) are refreshed via \Bindings.Update()\ when the
\ClipboardItem\ DependencyProperty changes. \Bindings.Update()\ forces
re-evaluation of all \x:Bind\ bindings regardless of mode, so \OneTime\
works correctly here.
## Validation
- [x] Full solution build passes (exit code 0)
- [x] Zero WMC1506 warnings after changes (was 13 before)
- [x] No behavioral changes — only binding mode optimization
