Answer 1

The MediaPlayer requires a Dispatcher in order to dispatch the MediaEnded, MediaOpened ... events.

When you are using a WinForm application a Dispatcher should already have been registered. That means that you should not have to do anything to get the events working.

If you want to receive events in a console application you'll have to run the Dispatcher yourself.

public static void Main (string[] args)
{
  var mediaPlayer = new MediaPlayer();
  mediaPlayer.MediaEnded += (sender, eventArgs) => Console.WriteLine ($"ended.");
  mediaPlayer.MediaOpened += (sender, eventArgs) => Console.WriteLine ($"started.");
  mediaPlayer.MediaFailed += (sender, eventArgs) => Console.WriteLine ($"failed: {eventArgs.ErrorException.Message}");
  mediaPlayer.Changed += (sender, eventArgs) => Console.WriteLine ("changed");

  mediaPlayer.Open (new Uri (@"S:\custom.mp3"));
  mediaPlayer.Play();

  Dispatcher.Run();
}

I also had this problem. I couldn't find a solution, but I did come up with a workaround if your media exists in a looping application or thread. You can just manually reset the position after a certain point.

if (media.Position > new TimeSpan(0, 2, 25))
      {
          media.Position = new TimeSpan(0, 0, 00);
      }

That's the best I can offer as of now.
