Internal Compiler Error: Could not load Avalonia.Visuals, Version = 0.9.0.0

[AIdrisy0139]

I recently upgraded my project from Avalonia version 0.10.13 to version 11.1.1. With this change any AXAML page that uses event binder throws the following error where it is trying to reference Avalonia.Visuals v 0.9.0.0.

In the solution explorer the package throws no errors or warnings.

Has anyone seen this issue before or have ideas on what I can check?

Actions Completed:

• Removed all nugget packages and re-installed them
• • I work in an offline environment so I just download all of the packages required via nuget.exe
• Ran dotnet restore on the solution
• Problem isolated to only appear when AXAML page has event binding

I think this is the same issue as #59. I did not realize that the latest 2.5.3 build does not support AV11. In a small test project I ran dotnet add package EventBinder.Avalonia --version 2.5.3-11.0.0-preview1 and the project works. I will test this in the main project tomorrow, and if it works, mark the issue closed.

Using the preview build worked.
