Expression Blend crashes when opening project / solution
Question
-
Hey, suddenly a solution/project started to crash when opening in Expression Blend. It compiles and runs fine using Visual Studio. Other projects works fine in Expression Blend, and this project worked fine earlier.
Using VS and EB SP1, and Windows 7 64-bit.
Debugging Blend.exe through VS gives this information:Error:
====================
An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.Expression.Project.dll Additional information: Object reference not set to an instance of an object.

Hi Beeblebrox,
An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.Expression.Project.dll Additional information: Object reference not set to an instance of an object.
It is a kind of normal exception. We cannot find out where it occurs according to your description. We highly recommend you comment your code part by part and then the properties. That will be the effiecient way. Thanks, please let me know the result.
Best regards,
Jonathan
