This has been asked recently
I had posted the link to the Issue in the thread : When will we use xaml designer view in WinUI 3.0?
Where is the designer view in WinUI 3?
I was developing uwp apps for the past few years, now moving to winui3. It is my first project. I am unable to find the designer view for the XAML files. Is it not available in WinUI3? or something else?
My Visual Studio 22 is up to date.

I think the only way to use the DESINER with WINUI3 or WINUI3 with the DESINER is: open two instances of VS Community Edition - in one, you will run UWP version of you project, and in another, you will run WinUI3 version. After setting up interface for UWP version you can share it with WinUI3, thanks to windows organizing in win10/win11.....
