From this window you can enter C# code and run it. You should have access to all classes you’ve defined in C#, JavaScript, or Boo in your project.

COMPATIBILITY

Tested on Unity 5.3.1, but should work on slightly earlier versions down to, perhaps 5.0.

Will definitely not work on older versions of Unity (4.x and below).

• Smooth out some hiccups with assembly reloads.
  • Local vars getting blown away.
