We've just shipped the latest stable version of WinUI 3, which is a part of Windows App SDK v0.8! This release includes lots of bug fixes and stability improvements. This version of WinUI 3 can be used for shipping production apps to the Microsoft Store.

Shipping WinUI 3 as a part of the Windows App SDK

In order to use this version of WinUI 3, you'll download the Project Reunion Visual Studio Extension (VSIX) to get started. The Project Reunion VSIX includes WinUI Project Templates that you'll use to build your WinUI 3 app, as well as access to other Windows App SDK components. The Windows App SDK package includes a reference to the WinUI 3 NuGet package.

For more on the Windows App SDK, see their documentation and repository. For installation instructions, see Set up your development environment.

NOTE: The Windows App SDK was previously known by the code name Project Reunion. Some SDK assets such as the VSIX extension and NuGet packages still use the code name, but these assets will be renamed in a future release. Some areas of this doc still use Project Reunion when referring to an existing asset or a specified earlier release.

What's new

These are all of the new changes in WinUI 3 since the release of Project Reunion 0.5.

  • The Pivot control has been added back in and can now be used in any WinUI 3 app.

  • All bug fixes from Project Reunion v0.5.5, v0.5.6, and v0.5.7 are included with this release.

  • The following types have been removed:

    • Microsoft.Graphics.IGeometrySource2D
    • Microsoft.Graphics.IGeometrySource2DInterop

    Please use Windows.Graphics.IGeometrySource2D and Windows.Graphics.IGeometrySource2DInterop instead.

  • All types in the Microsoft.System namespace have been moved to the Microsoft.UI.Dispatching namespace, including the DispatcherQueue class.

  • The AcrylicBrush.BackgroundSource property has been removed, since HostBackdrop is not supported as a BackgroundSource in WinUI 3.
