Which tool do you use to show/edit visual components?

[wl2776]

I've tried Visual Studio Code, Visual Studio (2022 community), Rider, both in Windows and in Linux, result is always the same.

When I click on any .axaml file in src/Views, I don't see anything.

When in Visual Studio, and VSCode, I see exceptions Dynamic code generation is not supported on this platform..
My bug report in Avalonia has been closed, and I was advised to use Rider.

Rider doesn't throw any exceptions, but only draws checkered sheet, without any previrew.

I found this log in Rider's idea.log, I think this is a problem in AvaloniaUI.

It's not an issue of Avalonia, but a mistake of mine. I removed the '$(Configuration)' == 'Release' condition to check AOT build.

I've fixed this issue. You can update your code to the latest develop branch.
