Windows App SDK 1.7.0 (1.7.25031001)

WinAppSDK 1.7.0 is the latest stable version of WinAppSDK providing new features and improvements to the platform.

Whats new in WinAppSDK 1.7.0:

• New Microsoft.UI.Windowing.AppWindow APIs make it easier to control your app windows to create a great experience. New capabilities include using:
  • SetTaskBarIcon and SetTitleBarIcon to independently set the taskbar and titlebar icons
  • AppWindowTitleBar.PreferredTheme to set the light/dark theme of the titlebar
  • using new properties like OverlappedPresenter.PreferredMinimumWidth
  • OverlappedPresenter.PreferredMaximumHeight to set a minimum or maximum width or height for the window.
• New Microsoft.Windows.Media.Capture.CameraCaptureUI API to WinAppSDK to provide a streamlined solution with feature parity, now supporting WindowID in the constructor for enhanced desktop compatibility.
• New OAuth2Manager API provides a streamlined solution for web authentication, offering OAuth 2.0 capabilities with full feature parity across all Windows platforms supported by Windows App SDK.
• New BackgroundTaskBuilder API provides WinAppSDK dependent apps the ability to directly register the full trust COM components with background tasks, removing the need to implement a workaround.
• TitleBar control makes it much easier to create a great, customizable titlebar for your app.
• RichEditBox now supports MathML, via RichEditTextDocument.SetMathMode and RichEditTextDocument.SetMathML.
• Windows App SDK's Dynamic Dependencies APIs delegate all calls to Windows 11's implementation when running on >= Windows 11 24H2 (10.0.26100.0) providing improved performance and robustness.
• Updates in the Microsoft.UI.Content namespace introduce several significant enhancements and new features aimed at improving the functionality and interoperability of the ContentIsland APIs.
  • DesktopPopupSiteBridge: Enables hosting a ContentIsland in the environment of a Win32 window with WS_POPUP style.
  • ChildSiteLink: Allows a parent ContentIsland to host a nested child ContentIsland, providing a seamless partitioning of the rendering surface without user experience seams.
  • DesktopAttachedSiteBridge: Attaches to an existing Win32 window instead of creating a new one, designed to host a ContentIsland with Windows.UI.Composition.Visuals at the root of the Win32 window hierarchy, ensuring full control over Win32-based input processing and accessibility.
  • Enhanced rendering and input synchronization
  • ContentIslands with Windows.UI.Composition.Visuals
• New RuntimeCompatibilityOptions support will allow more control over how servicing changes affect apps. For more info, see GitHub #4966.
• A new ReleaseInfo API provides easy access to the version of the Windows App SDK Runtime in use. For more info, see GitHub #2893.
• Note: Windows Copilot Runtime APIs are not included this release. To experiment with these APIs, please continue to use the 1.7-experimental3 release and share your feedback!
