c# - Missing code from class diagrams, auto-repair fails? -

Okay, this is driving me crazy: I have a visual studio project, which is with some class diagrams that are apparently "broken". When I open them, I get this signal:

I click on "Yes", and Visual Studio talks about it - it takes a moment, maybe 10-20 seconds is the problem that every time I shut down and open the picture!

Any suggestions?

I recommend that you delete that class diagram and create a new one ...
