What does !!0 refer to when I get a "MissingMethodException" error?

Question

I'm helping my company upgrade from VS 2008 to VS 2010. Somewhere in the middle of all the testing, I'm getting a MissingMethodException saying "Method not found: '!!0 (namespace).(etc).(etc).(function(parameter))'."

Does the '!!0' provide any sort of clue that anyone knows of (Google doesn't recognize exclamation points in its searches)?

Obviously, working in VS 2010
VB.Net 4

Looks like obfuscation to me.
