我一直在尝试按照CodeProject上的"Asp.Net SignalR聊天室"教程(http://www.codeproject.com/Articles/562023/Asp-Net-SignalR-Chat-Room)实现聊天室.但是,我收到错误"Hubs.ChatHubs.OnDisconnected():找不到合适的方法来覆盖"

            // send to caller
            Clients.Caller.onConnected(id, userName, ConnectedUsers, CurrentMessage);

            // send to all except caller client
            Clients.AllExcept(id).onNewUserConnected(id, userName);

        }

    }

    public void SendMessageToAll(string userName, …
