Respond to the connection events (events are registered in the above example):

    public class ConnectionEventsSink : IMbnConnectionEvents
    {
        public ConnectionEventsSink() { }

        public void OnConnectComplete(IMbnConnection connection, uint requestID, int status)
        {
            // Un-register the connect event - you might not want to do this, depends on your own requirements. Do do this you need the cookie uint from when the events were registered.
            MbnConnectionManager connMgr = new MbnConnectionManager();
            IConnectionPointContainer connPointContainer = connMgr as IConnectionPointContainer;

            Guid IID_IMbnConnectionEvents = typeof(IMbnConnectionEvents).GUID;
            IConnectionPoint connPoint;
            connPointContainer.FindConnectionPoint(ref IID_IMbnConnectionEvents, out connPoint);

            connPoint.Unadvise(cookie);

            switch (status)
            {
