We are using IE8 and loading a XBAP application. It works majority of times but sometimes we see this "Windows Presentation Foundation Host has encountered a problem and needs to close" at the time of initializing the application. This stack trace is from Event Viewer. I'm completely lost what could be causing it. Please Help! Thanks
Application: PresentationHost.exe
Framework Version: v4.0.30319
Description: The application requested process termination through System.Environment.FailFast(string message).
Message: Unrecoverable system error.
