Top level exception handling in C#

I want to do some logging and allow the users to unwind in the event that a truly exceptional unexpected event comes up and to avoid showing the users an Unhandled Exception.  I would like to roll the changes up the call stack to the top level so I can have a full stack trace.  Here's what I've added, but it doesn't seem to be firing on exceptions.


AppDomain currentDomain = AppDomain.CurrentDomain;
                currentDomain.UnhandledException += new UnhandledExceptionEventHandler(currentDomain_UnhandledException);
                Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
 
void  Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
            {
                   //method to call my error class
            }
 
        void currentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            //method to call my error class
        }

Using .NET 2.0 you can use Application Level Events.  One of these events is OnUnhandledException  If you put your exception handling code in this event you should accomplish what you need to do.
