Scope and APIs

Primary WinUI APIs:

• ListView, GridView, SelectionMode, IsItemClickEnabled, ContainerStyle

Primary Avalonia APIs:

• ListBox, SelectingItemsControl, SelectionMode, ItemTemplate, styles

Concept Mapping

WinUI idiom	Avalonia idiom
WinUI control and state pipeline	Avalonia control themes, selectors, and transitions
WinUI command/input surfaces	Avalonia commands + KeyBinding/routed input
WinUI resource/theme flow	Avalonia resource dictionaries + ThemeVariant

Conversion Example

WinUI XAML:

<ListView ItemsSource="{x:Bind ViewModel.Items}" SelectionMode="Multiple" IsItemClickEnabled="True" />

WinUI C#:

listView.SelectionChanged += OnSelectionChanged;

Avalonia XAML:

<ListBox ItemsSource="{Binding Items}" SelectionMode="Multiple" />

Avalonia C#:

listBox.SelectionChanged += OnSelectionChanged;

Migration Notes

1. Preserve behavior and interaction contracts before visual refinements.
2. Port hot paths with explicit UI-thread and invalidation discipline.
3. Prefer typed compiled bindings and deterministic state flow in migrated views.
