About this tag
Microsoft.UI.Reactor is covered here as an experimental C# framework for building WinUI desktop apps, not a replacement UI platform. The tagged discussion explains that Reactor draws no pixels of its own and renders real WinUI controls such as Button, TextBox and NavigationView, while Microsoft offers no support policy or API guarantees for the preview.

Readers interested in Windows desktop development with C#, WinUI and early Microsoft tooling will find the most relevant material under this tag.
