Ummm...  That's true, but misleading.  Whether you use mono mdk, or windows visual studio, of course it's incomplete because, there's an entire internet of libraries out there (just browse NuGet a little bit).  It is normal, and must be assumed, that only the base standard libraries are present in a default installation.  You always have to add on assemblies specific to your project -

In this case, it sounds like you were missing nuget (pkgconfig) so it wasn't downloading the winforms assembly for you.
