How do I handle unhandled Application level exceptions in a WPF application?

Hi:

I'm migrating an existing Winforms based application to WPF.

For handling unhandled exceptions at the application level in my Winforms app, I did the following:

// Added for application level error handling
Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException);
// This is a delegate! That is a user method inside the parens
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
// This is a delegate! That is a user method inside the parens
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);

How do I go about handling these conditions in a WPF based application?

Thanks,
JohnB

Unless you are using threads you can use something like this

Michael

         
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler((o, e) => { 
            UnhandledException((Exception)e.ExceptionObject);

// Unhandled exceptions
static void UnhandledException(Exception e) {
   System.Windows.MessageBox.Show("An error has occurred and the program will now exit" + "\r\n" +
                                                            "Error Message:" + "\r\n" +
                                                            e.Message + "\r\n\r\n" +
                                                            e.StackTrace);
   Application.Exit();
 }

OK. This is what I was doing in my Winforms app.
How would I handle exceptions thrown within threads (either my own, or spun from 3rd party libraries)?
