Remoting: assign a client handler to a remote event

[124256]

I'm trying to get an event-handler relationship set up over a remote tcp connection. I have set the security level so that I can serialize any object (full). My server has a "game" object which has an event. The client has a user control that responds to the event through an intermediate "remoteReceiver " object that inherits MarshallbyRefOb ject. I'm getting "An error occurred while processing the request on the server: System.Argument NullException: No message was deserialized prior to calling the DispatchChannel Sink." at "Game.testE vent += new Game.BlankEvent Handler(remoteR eceiver.fireTes tEvent2);". Can anyone tell me how to fix this.

Server Code:

[Serializable]
    public class Game : MarshalByRefObject
    {
        public Game()
        {
            // We create our own provider because we need to set the TYpeFilterLevel to full
            // Without this, we can not pass objects to remote procedure calls.
            SoapServerFormatterSinkProvider provider = new SoapServerFormatterSinkProvider();
            provider.TypeFilterLevel = TypeFilterLevel.Full;
            IDictionary props = new Hashtable();
            props["port"] = Properties.Settings.Default.tcp_channel;
            props["name"] = String.Empty;//"game";
            // Register our channel on selected port
            ChannelServices.RegisterChannel(new TcpChannel(props, null, provider), false);
            // Register as an available service with the name 
            RemotingServices.Marshal(this, "game");
        }
        [Serializable]
        public delegate void BlankEventHandler();
        public event BlankEventHandler testEvent;
 
        public void fireTestEvent()
        {
            testEvent();
        }
 

Client Code:

          // Connect to the game server
            TcpChannel tcpChannel = new TcpChannel();
            ChannelServices.RegisterChannel(tcpChannel, false);
            Type requiredType = typeof(Game);
            string port = Properties.Settings.Default.tcp_channel.ToString();
            Game game = (Game)Activator.GetObject(requiredType, "tcp://" + ip + ":" + port + "/game");
 
            remoteReceiver = new RemoteReceiver();
 
            game.testEvent += new Game.BlankEventHandler(remoteReceiver.fireTestEvent2);
            remoteReceiver.testEvent2 += new Game.BlankEventHandler(eventResponder);
            game.fireTestEvent();
