## Windows CollectionView handler in .NET 11

In .NET MAUI 11, Windows uses the `Microsoft.Maui.Controls.Handlers.Items2.CollectionViewHandler2` handler for <xref:Microsoft.Maui.Controls.CollectionView> by default. The handler is controlled by the `Microsoft.Maui.RuntimeFeature.IsWindowsCollectionView2HandlerEnabled` <xref:System.AppContext> switch, which is on by default. The `UseWindowsCollectionView2Handler` MSBuild property maps to this switch.

This WinUI `ItemsRepeater`-based handler improves virtualization and scrolling behavior, and aligns the Windows <xref:Microsoft.Maui.Controls.CollectionView> architecture with the optimized handlers on other platforms. Selection visuals are also different from the legacy Windows handler: selected items are highlighted with a border that wraps the item, and the multiple-selection UI differs from the previous `ListView`-based handler.

If your app depends on legacy Windows <xref:Microsoft.Maui.Controls.CollectionView> behavior or custom handler assumptions, temporarily opt out while migrating by setting the `UseWindowsCollectionView2Handler` MSBuild property to `false` in your project file:

```xml
<PropertyGroup>
<UseWindowsCollectionView2Handler>false</UseWindowsCollectionView2Handler>
</PropertyGroup>
```
