Windows App SDK 1.7.1 (1.7.250401001)

WinAppSDK 1.7.1 is the latest stable version of WinAppSDK providing new features and improvements to the platform.

Whats new in WinAppSDK 1.7.1:

• Improved the telemetry for failure scenarios in WindowsAppRuntimeInstall-<arch>.exe. For more info, see GitHub issue #5289. (RuntimeCompatibilityChange: N/A for this installer change)
• Fixed an issue where pointer input would stop working when using arrow keys at the same time. For more info, see GitHub issue #10126. (RuntimeCompatibilityChange: FixStuckPointerInputQueue)
• Fixed an issue where apps in remote desktop stop responding to pointer input. For more info, see GitHub issue #10009. (This is the same fix as the pointer input plus arrow keys fix, due to remote desktop automatically sending some key input during the switch away and back.) (RuntimeCompatibilityChange: FixStuckPointerInputQueue)
• Fixed a potential crash trying to restore focus if a window activation event is delivered for a window which is closing. (RuntimeCompatibilityChange: FixWindowCloseFocusCrash)
• Fixed a performance regression introduced in WinAppSDK 1.6 due to WinUI binaries missing some linker optimizations. (RuntimeCompatibilityChange: N/A, changed linker options)
• Fixed a potential crash if ProgressBar::SetProgressBarIndicatorWidth is called on a ProgressBar which is not in the tree. (RuntimeCompatibilityChange: FixSetProgressBarIndicatorWidthCrash)
• Fixed a potential crash caused by CPopup::EnsureBridgeClosed sometimes triggering reentrancy. (RuntimeCompatibilityChange: FixPopupClosingReentrancyCrash)
• Fixed a potential crash when closing a popup due to CUIElement::FlushPendingKeepVisibleOperations using a null children collection. (RuntimeCompatibilityChange: FixPopupUnloadingCrash)
• Fixed PackageDeploymentManager.EnsurePackage*Ready to ensure version supersedence. For more info, see GitHub issue #5191. (RuntimeCompatibilityChange: EnsurePackageReadyVersionSupercedence)
• Fixed a potential crash caused by WebView2::UpdateCoreWebViewVisibility sometimes triggering reentrancy. For more info, see GitHub issue #10305. (RuntimeCompatibilityChange: FixWebViewVisibilityReentrancyCrash)
• Fixed an issue where app UI sometimes permanently freezes and can stop rendering due to the DispatcherQueue getting stuck. (RuntimeCompatibilityChange: FixRandomUIFreezeInDispatcher)
