SignalR OnConnected - Sending Connected Client a Message

Very simple question. Why does the client that has just connected not receive any messages, but all other clients get the broadcast? What's the correct way of sending the client that connected a message?

protected override void OnConnected(HttpContextBase context, string clientId)
{      
    GameAction message = new GameAction();
    message.text = "Player connected";
    Connection.Broadcast(serializer.Serialize(message));

    GameAction gamestate = new GameAction(); 
    gamestate.text = "Some client specific info";     
    Send(clientId, serializer.Serialize(gamestate));      
}
