I am having a problem with Visual Studio 2010 crashing when opening a WPF user control on one computer. Whenever I open any WPF user control or try to create a new WPF user control in our product solution (any project in the solution), Visual Studio crashes.
I have uninstalled or disabled all Visual Studio add-ins (such as ReSharper and .NET Reflector) and reinstalled Visual Studio 2010 itself (along with Silverlight and the .NET Framework 4.0), but this has not helped.
I can create a new WPF solution and the WPF editor starts successfully for the newly created window. However, on other similarly configured computers, we can successfully open the user controls in our product solution so it does not appear to be a problem with the solution or user controls themselves.
The information in the error report for the crash looks like this:
EventType : clr20r3 P1 : devenv.exe P2 : 10.0.30319.1 P3 : 4ba1fab3
P4 : microsoft.visualstudio.shell.10.0 P5 : 10.0.0.0 P6 : 4ba1e1f5
P7 : 506 P8 : 13 P9 : system.argumentnullexception
If I debug Visual Studio during the crash, the call stack for the crash looks like this:
