Microsoft today announced the release of WinUI 3.0 feature roadmap. The feature roadmap table included below will offer you the status on WinUI 3 features, and the expected date of availability. As you can expect from any project development, there might be changes in the below plan. You can check the source link periodically for latest updates.
WinUI 3 is a UI layer that takes the decoupled UWP XAML Visual Layer, the WinUI 2 library, and combines it with more modern features and capabilities. This layer can be used in any Desktop app or UWP app.
