Visual Studio 2022 17.3.6 Xaml Designer 未针对 UNO 平台显示

Question

I've followed Get Started on Visual Studio 2022 UNO platform guide. Then I've created new app with the following plaftorms:

When I try to open Xaml designer for MainPage.xaml - is is not appearing:

As you can I've selected WinUI project in a top-left dropdown as adviced here - with no success.

How to make Xaml Designer appear? Thank you in advance.

Answer 1

Unfortunately, there is no XAML Designer for the new WinUI 3.0 (although there was one for the old UWP, which is what's referred to in the advice link that you found). So it's not exactly a problem of UNO Platform.

In fact, there is an open issue on GitHub which was opened more than a year ago, and the problem still remains: Discussion: WinUI 3.0 XAML Designer #5917

And, apparently, it isn't even in the roadmap: Windows UI Library Overview

Finally, there is a previous question here regarding this topic: Where is the designer view in WinUI 3?
