System.ComponentModel.Design.ExceptionCollection

Question

I\'m using the Ribbon control located on CodePlex, and following the tutorial located here . Once I add the reference, and the proper code in the designer I get this error w

Answer 1

Let me add two more cases when such exception can happen, along with when control tries to do something that is not allowed under design mode:

1. When it's impossible to compile the user control.
2. When designer code contains multiple similar (or identical) lines with initialization of same controls or properties, this can easily happen on merge.

All that cases produce same extremely meaningful error message, and in this particular two debugging of Visual Studio won't help, so I just ended up with bisecting my designer code.
