Catastrophic Faillure and Delay Notification issues with WCF
Before adding some new functionality to a customer’s existing site, my development runtime environment would hang, throw a timeout exception and after about a minute later a Catastrophic Failure message would appear. I also noticed a Visual Studio icon appeared in my system tray giving me a Delay Notification message. So I set break points at the entry points of the possible services having an issue but the code would never get executed. After turning on Service Tracing and sifting through tons of information, I found the issue and saw this in the Tracing Viewer (bold text below is key): <E2ETraceEvent xmlns="http://schemas.microsoft.com/2004/06/E2ETraceEvent"> <System xmlns="http://schemas.microsoft.com/2004/06/windows/eventlog/system"> <EventID>458797</EventID> <Type>3</Type> <SubType Name="Information">0</SubType&g
