Run -> Start Debugging Greyed Out

Hey all,

Running a MonoGame Windows OpenGL project (v3.01) on Xamarin Studio v4.01, and I can't debug for some reason. This is becoming increasingly problematic as the project gets more complex.

I just tested a new empty project, in case the issue is with the MonoGame templates, but still I cannot use debugging in Xamarin Studio.

Do you guys have any ideas?
