Microsoft publishes Windows UI (WinUI) Library Release Roadmap


According to Microsoft, WinUI 3 will release as a series of preview releases throughout 2020, culminating with v3.0 shipping in 2021. Creating a new WinUI 3 app will be easy using the new Visual Studio 2019 project templates. For existing UWP XAML apps, there will be some updates required when migrating to WinUI 3. These updates will require little effort, with the bulk of most project changes involving find-and-replace namespace changes.
