Windows App SDK 1.8.11 (1.8.260804001)

WinAppSDK 1.8.11 is the latest stable servicing release for 1.8, with fixes for Storage Picker focus restoration, MRT Core fallback paths, and Windows App Runtime base-directory isolation.

Bug fixes:

Bug Fix Runtime Compatibility Change
Fixed an issue where the Storage Pickers (FileOpenPicker, FileSavePicker, and FolderPicker) left the calling WinUI app window without keyboard focus after the file dialog closed. The app now restores its previous focus. See GitHub issue [#6505]. StoragePickers_RestoreFocusAfterDialogCloses
Fixed a regression where MrmGetFilePathFromName returned ERROR_FILE_NOT_FOUND when the PRI file didn't exist instead of returning the documented fallback path. See GitHub issue [#5940]. ResourceManager_RestoreDefaultFallbackPath
Fixed an issue where MICROSOFT_WINDOWSAPPRUNTIME_BASE_DIRECTORY could be inherited by child processes, disrupting MRT Core and catalog lookups. See GitHub issue [#5987]. WindowsAppRuntime_BaseDirectoryIsolation
