This is not fatal because it only happens if I set "When the exception is thrown" setting to "Break into debugger" in the "Exceptions" window of Visual Studio. However, it is inconvience debugging point of view. Any ideas how to suppress this exception?


A first chance exception of type 'System.NullReferenceException' occurred in actiprosoftware.shared.dll

Additional information: Object reference not set to an instance of an object.

I'm not seeing it happen... what exactly are you doing to cause it to occur? Please give detailed steps.

OK. I built a simple test application where I tried to reproduce this occurrence. I didn't get the exception in that application. It seems that there is some unknown combination in my "real" application that causes this. I'll come back when I know more... Probably, the problem is on my side.
