I'm trying to convert my project from Xamarin.Mac mobile to Xamarin.Mac 4.5.
Now I get errors with drawing. When building it says that System.Drawing.Color is referenced multiple times and if I look at the System.Drawing and the OpenTK assemblies, they both contain a Color class. Did anyone else run into this?I may be using the wrong System.Drawing assembly.
Minimal csproj: (from new test project)

So I'm mixing two assemblies that are not compatible.
So I need to 'build' a new System.Drawing.dll for Xamarin cycle 9?
Is this System.Drawing approach even a reasonable choice for drawing simple 2D thing on screen?
This is what I'm using it for:
