"Unable to find type" XAMLIL error message after deleting window from project

See original GitHub issue

This is a weird one. Versions: AvaloniaUI 0.10.0-pre6, Avalonia for Visual Studio 0.9.11.0

Steps:

Create a new Avalonia Project (doesn’t matter if MVVM or not)
Right click project -> add a new Window
Don’t change the name of the window, will be named Window1.axaml
Delete the Window by deleting the file Window1.axaml. This deletes both Window1.axaml and Window1.axaml.cs.

Try to compile the solution. An error message occurs: Unable to find type AvaloniaApplication1.Window1 Line 1, Position 2.

Grep the entire solution for Window1. No result.

Clean and rebuild the solution. The error persists.

Workaround I found:

Add a window with the same name again.
Rename the window. Only now will the window name show up in the csproj file
Delete the renamed window.

Now everything compiles fine again.

This issue seems to appear fairly frequently lately and basically means that deleting XAML files without changing a line of code in a project will end up with this error.

Also in my case forcing 20+ devs to wipe their repo and rebuild for 10 minutes is not the greatest option. @kekekeks Are you going to have time to investigate this sometime?

MSBuild is doing the same for Compile items: https://github.com/dotnet/msbuild/blob/f0eebf2872d76ab0cd43fdc4153ba636232b222f/src/Tasks/Microsoft.Common.CurrentVersion.targets#L3529-L3548
