Navigation in the application Activating Windows Phone 7 (Tombstoning)

Question

Whenever my program is closed using overhead storage, when it is activated, I want the application to move back to the start screen.

I would like to do something like this

private void Application_Activated(object sender, ActivatedEventArgs e) { NavigationService.Navigate(new Uri("/Start.xaml", UriKind.Relative));
}

but that will not work. Thank you, Shureman.
