Windows App SDK 2.0-Experimental4 (2.0.0-experimental4)

WinAppSDK 2.0.0 Experimental 4 is the latest experimental version of WinAppSDK providing new features and improvements to the platform.

What's new in WinAppSDK 2.0 Experimental 4:

  • Onnx Runtime updated to mainline version 1.24 for improved compatibility and stability.
  • Decreased the size of Microsoft.Windows.AI.MachineLearning.dll by approximately 160 KB
  • Introduced new APIs to lookup statistics of items being indexed.
  • New support for query cancellation to allow apps to run a query and update it if there is a new query.
  • Video Scaler is now disposable, improving resource management and lifecycle control.
  • The Video Super Resolution model is now compiled and cached to improve performance and reduce repeated initialization costs.
  • Removed the requirement for explicit WinML initialization when using Video Super Resolution.
  • The FlowLayout control now uses ItemSpacing and LineSpacing terminology.
  • The WrapPanel control now uses ItemSpacing and LineSpacing terminology.
  • Implemented the IXamlPredicate interface to define custom predicates that integrate seemlessly with XAML's conditional namespace syntax.
  • Added WinUI tools and scripts for use by external developers to build and test Windows.
  • Deprecated the DependencyObject.Dispatcher API in WinUI.
  • Deprecated the Window.Current API in WinUI.
  • Deprecated FocusManager.GetFocusedElement API in WinUI.
  • Renamed the SystemBackdropHost to SystemBackdropElement in WinUI.
  • Renamed the Microsoft.Windows.AI.Search.Experimental.AppContentIndex namespace to Microsoft.Windows.Search.AppContentIndex.

Bugs fixed:

  • Fixed “Class not registered” errors when using self-contained deployment with Windows ML. Developers using self-contained deployment no longer need to register all the Foundation package activatable classes that were used internally.
  • Fixed a potential crash occurring on process shutdown when using Windows ML.
  • Fixed the ImageForegroundExtractor API routing path so calls reach the correct endpoint.
  • Ensured execution provider install and download progress is correctly forwarded to apps during package deployment.
  • Fixed a crash in SystemBackdrop when the target disconnects by guarding invalid disconnection paths.
  • Fixed an issue that prevented Windows AI APIs from being available for some devices.
