Windows App SDK 1.7.4 ( 1.7.250909003 )
WinAppSDK 1.7.4 is the latest stable version of WinAppSDK 1.7 providing new features and improvements to the platform. To see everything that's new and changed, see the full Windows App SDK 1.7 release notes.
This release also includes the following Bug Fixes:
| Bug Fix | Runtime Compatibility Change |
|---|---|
| Fixed an occasional crash in DirectUI::PointerRoutedEventArgs::GetCurrentPointImpl | GetIntermediatePointsImpl_Crash |
| Apps with an incorrect activation manifest no longer crash in certain situations but instead return an error | DesktopSiteBridge_ActivationErrorCrash |
| NavigationView: Fixed a bug where setting SelectedItem as null did not correctly clear the selection state in collapsed mode | NavigationView_ClearSelectedItem |
| Fixed an issue where the hover effects of other windows for the app could flicker when at least one window had ExtendsContentIntoTitleBar set to true | XamlIsland_ExitNonClientArea |
| Fixed certain corrupted upgrade scenarios from 1.6 to 1.7 by ensuring version numbers on certain binaries are consistently increasing. | N/A, file version change |
| Fixed an issue where UnhandledExceptions were not being propagated to managed code | DispatcherQueue_PropagateException |
| Fixed an issue where resizing the window would fire an AppWindow.Changed event with AppWindowChangedEventArgs.DidPresenterChange set to true | AppWindow_NoDidPresenterChangeOnRestore |
| Fixed a potential crash on window close if an InputPointerSource is disposed during certain reentrant scenarios | InputPointerSource_ReentrantDisposedCrash |
| Fixed an issue where the installer failed to update the Singleton package if an older version was running in the background. The fix ensures AddPackage is always called with ForceTargetAppShutdown for the Singleton and restarts the NotificationLongRunningPlatform to complete the update. | N/A, installer change |
