WinUI 3 in WinAppSDK 2.2.0

WinUI 3 in Windows App SDK 2.2.0

This release of WinUI 3 ships as part of Windows App SDK 2.2.0. To use it in your app, install the Microsoft.WindowsAppSDK 2.2.0 NuGet package.

What's new in WinUI 3:

• New XamlBindingHelper boxing-free setter overloads. New SetPropertyFromThickness, SetPropertyFromCornerRadius, and SetPropertyFromColor overloads on XamlBindingHelper let {x:Bind} set value-type properties without boxing. The Setter.ValueProperty dependency property is also now exposed.

Bug fixes:

• Fixed a crash in RenderTargetBitmap when the target element leaves the visual tree (for example, a popup closes) before PreCommit completes. RenderAsync now returns E_ABORT instead of crashing.
• Fixed a use-after-free crash in ScrollView when the control is destroyed while its hide-indicators timer tick is still pending. See microsoft/microsoft-ui-xaml#10514.
• Fixed a potential crash in Microsoft.UI.Xaml.dll!DirectUI::DXamlCore::GetPeerPrivate caused by attempting to access an object scheduled to be freed.
• Fixed an issue where Microsoft.UI.System.ThemeSettings could crash an app if it was destroyed on a background thread (for example, when destroyed by the .NET garbage collector).
• Fixed a crash that could occur on certain devices when active touch contacts were canceled by input hardware, such as when pen input overrides them.
