I want to make a Class Library (.NET Standard) and I'm using System.Drawing, but I get the error: 

CS0246 C# The type or namespace name 'Bitmap' could not be found 
(are you missing a using directive or an assembly reference?)

I'm using .NET Standard 2.0.

I'm the author of CoreCompat.System.Drawing. If you're on .NET Core 2.0, I'd recommend you'd move to System.Drawing.Common instead, which is the Microsoft-maintained implementation of System.Drawing for .NET Core.

If you're on Linux or macOS, make sure to install libgdiplus. On macOS, run brew install mono-libgdiplus; on Linux your package manager should provide you with a libgdiplus package.
