Create Image or Bitmap in console application - can't seem to find System.Drawing?
https://stackoverflow.com/questions/13784559/create-image-or-bitmap-in-console-application-cant-seem-to-find-system-drawin
    You have to add Reference to the system.Drawing.Dll in your project.
    Right click on Project, add reference and find System.Drawing.DLL and add reference.
    EDIT: You will find it under Assemblies->Framework->System.Drawing
