If you look at the event handler for the UnhandledException of the
Application object in your App.xaml.cs file, you'll see why. By default,
unhandled exceptions are handled differently when a debugger is attached.
private void Application_UnhandledException(object sender,
ApplicationUnhandledExceptionEventArgs e)
{
// If the app is running outside of the debugger then report
the exception using
// the browser's exception mechanism. On IE this will display
it a yellow alert
// icon in the status bar and Firefox will display a script
error.
if (!System.Diagnostics.Debugger.IsAttached)
{
// NOTE: This will allow the application to continue
running after an exception has been thrown
// but not handled.
// For production applications this error handling should
be replaced with something that will
// report the error to the website and stop the application.
e.Handled = true;
Deployment.Current.Dispatcher.BeginInvoke(delegate {
ReportErrorToDOM(e); });
}
}
