NullReferenceException in WaitForWaitHandle
-
Hi All, My C# - VS2005 Application occasionally gives the NullReferenceException when the application is being debugged in Relase mode. It occurs when the program is left idle in debug mode for a long time around 30min. Any idea why such an error could occur? Please find the call-stack of the error.
