Error CS0012: The type 'Color' is defined in an assembly that is not referenced

Got an error during build on CI

Error: Test.cs(16,9): error CS0012: The type 'Color' is defined in an assembly that is not referenced. You must add a reference to assembly 'Avalonia.Visuals, Version=0.10.0.0, Culture=neutral, PublicKeyToken=null'. [/home/runner/work/CSharpMath/CSharpMath/CSharpMath.Xaml.Tests.NuGet/CSharpMath.Xaml.Tests.NuGet.csproj]

I wasn't able to reproduce it locally though. But I tested only on Windows.

Any ideas are welcome I haven't a clue why it happens.

You have some dll built for 0.9.x branch (it might be a nuget reference). Recompile everything to 0.10.0.

[FoggyFinder]

No, but there is a reference to 0.10.0-preview5 version. And since 0.10-rc version they are not compatible, right? Is so then I suppose it is not a bug but expected behavior.

Ah, yes, strong naming was first added in rc1
