Xaml Islands state WINUI + wpf

[rmarinho]

IS there a experimental package to try WINUI3 with wpf app ?

WinUI 3 XI (xaml island) is not ready. You could use WinUI 2 XI as that's what Windows 11 uses all over the place. (new taskmgr , File Explorer and so on).
see #2233 (comment) and upvote in their roadmap https://portal.productboard.com/winappsdk/1-windows-app-sdk/c/9-xaml-islands-use-winui-3-from-wpf-or-winforms

and try to use the github search function.
