Hi,
Inheriting an in-house Silverlight app. It randomly crashes while debugging in Visual Studio 2015. I have fixed several crash scenarios, related to MessageBox windows shown on a non-UI thread before the RootVisual is initialized, and changed the WCF Services to streaming to avoid OutOfMemoryException crashes. However, I still have one crash scenario remaining, and I can't figure out for the life of me what the issue is.
Put simply, the app crashes (almost) immediately after the XAP is downloaded.
Below is a pretty typical Output window for a crash. Also, it is not 100% reproducible every single time, and does not (currently) happen in Production.
--> I NEED help with steps to further diagnose this last crash. It is a HUGE productivity time sink to repeatedly click Run New Instance in the debugger and hope I get a run that doesn't crash. <---
Key line:
The program '[28556] iexplore.exe: Silverlight' has exited with code -805306369 (0xcfffffff) 'Process was unresponsive and was terminated'.
