// Listen to all notifications posted for any object
var token = MPMoviePlayerController.Notifications.ObserveLoadStateDidChange ((notification) => {
	Console.WriteLine ("Observed LoadStateDidChangeNotification!");
};

// Listen to all notifications posted for a single object
var token = MPMoviePlayerController.Notifications.ObserveLoadStateDidChange (objectToObserve, (notification) => {
	Console.WriteLine ($"Observed LoadStateDidChangeNotification for {nameof (objectToObserve)}!");
};

// Stop listening for notifications
token.Dispose ();
