UnhandledExceptionEventHandler not catching System.NotImplemented exception

My c# program implements a unhandledExceptionEventHandler. Still, one of the libraries that I use throws up a NotImplemented exception. Windows promptly throws up a dialog box whether I want to continue or exit. How do I catch this exception (so that I can exit without prompting the user?)

If you are working on VS2010, simply go to the Debug menu and hit Exceptions.... Now check every exception on Thrown. Run your program again from IDE on Debug mode. Now your program will stop on every exception. You will be able to identify what's happenning when you are exiting.

It is more straightforward to wrap your entry points with try ... catch than to use the handler, but anyway. If you are debugging from an IDE, those dialog boxes correspond to the beginning of processing of the exception, whereas the UnhandledExceptionEventHandler only gets a chance to execute after the stack has been completely unrolled, at the end of the same process, and when there is nothing left on that unfortunate thread for debugging. You should be able to disable the unwanted dialog in your IDE (for example, like this).
