Silverlight
|parent-child
I get the folowing error in my Silverlight application. But i cant figure out what control it is that is the problem. If i debug it don't break on anything in the code, it just fails in this framework callstack with only framework code. Is there any way to get more information on what part of a Silverlight app that is the problem in this case.
