I have the same problem with incompatibility with net7.0 after upgrading to it from .netcore3.1 for some unit test projects in our Xamarin solution because it will stop being supported at some point. Did you find any workaround?

I experience the same issue, but was able to find a temporary workaround by first removing the SkiaSharp packages from the solution, restoring nuget packages and then re-adding SkiaSharp. Package restore still fails after the last step, but at least I can restore the rest of my packages and run my solution again.

Hey, I've found a workaround: just add packages to your test project with IncludeAssets="None".

<!-- SkiaSharp not compatible with .NET >= 6.0.2xx https://github.com/mono/SkiaSharp/issues/2335 -->
<PackageReference Include="OpenTK" Version="3.0.1" IncludeAssets="None" GeneratePathProperty="true" />
<PackageReference Include="OpenTK.GLControl" Version="3.0.1" IncludeAssets="None" GeneratePathProperty="true" />

If you really need those DLL linked in the test project, you can add something like this:

<Reference Include="OpenTK">
  <HintPath>$(PkgOpenTK)\lib\net20\OpenTK.dll</HintPath>
</Reference>

Or you can just try to include OpenTK 4.x.x in your test project and see if that'd be enough.
