ADS 11 event notifications to .net client

I need to receive event notifications created via sp_CreateEvent(....) in an .net (c#) client.

Is waiting for an event ( EXECUTE PROCEDURE sp_WaitForEvent( ‘my_event’, 2000, 0, 0 ); )  - so actually polling - the only way to receive the notification or will AdsConnection.InfoMessage be fired as well?

Thanks
