It is permission issue in my case the task scheduler has a user which doesn't have permission on the server in which the database is present.

Hans Passant was correct, I added a handler for AppDomain.CurrentDomain.UnhandledException as described here http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception(v=vs.71).aspx I was able to find the exception that was occurring and corrected it.

Another option is to simply use the Application log accessible via the Windows Event Viewer. The .Net error will be recorded to the Application log.

You can see these events here:

I encountered this problem when working with COM objects. Under certain circumstances (my fault), I destroyed an external .EXE process, in a parallel thread, a variable tried to access the com interface app.method and a COM-level crash occurred. Task Scheduler noticed this and shut down the app. But if you run the app in the console and don't handle the exception, the app will continue to work ...

Please note that if you use unmanaged code or external objects (AD, Socket, COM ...), you need to monitor them!

I got the same error but I have fixed it by changing the file reading path from "ConfigFile.xml" to AppDomain.CurrentDomain.BaseDirectory.ToString() + "ConfigFile.xml"

In my case, this error due to file path error because task manager starts program from "System32" as initial path but the folder we thought.
