关于Remoting信道的通信的问题

我是今年才毕业的应届生，找了一家公司，主要从事.net开发。公司让我从事Remoting开发，最近几天看了wayfarer的一些文章，觉得很好，自己也试着做了一个小程序，不知道为什么达不到预期的效果。
现在把程序发上来，希望大家能为我解决问题。
远程类：

using  System;
using  System.Runtime.Remoting;

namespace  Distribution_Framework
{
    //定义广播事件的参数类
    [Serializable]
    public class BroadcastEventArgs : EventArgs
    {
        private string msg = null;
        public BroadcastEventArgs(string message)
        {
            msg = message;
        }
        public string Message
        {
            get
            {
                return msg;
            }
        }
    }
    public delegate void BroadcastEventHandler(object sender, BroadcastEventArgs submitArgs);
    public class InfoCenter : MarshalByRefObject
    {
        private static int count= 0;
        public InfoCenter()
        {
            count = count+1;
            Console.Write(count.ToString());
            Console.WriteLine("InfoCenter created.");
        }
        public override object InitializeLifetimeService()
        {
            return null;
        }
        public event BroadcastEventHandler Broadcaster;
        public void Broadcasting(string message)
        {
            BroadcastEventArgs e = new BroadcastEventArgs(message);

            if (Broadcaster != null)
            {
                Broadcaster(this, e);//发出事件
                Console.WriteLine("Broadcast:" + e.Message);
            }
        }
    }
}

服务端：

            sinkProvider.TypeFilterLevel =TypeFilterLevel.Full;

            ChannelServices.RegisterChannel(channel);*/

            Console.WriteLine("Server is running, Press Enter key to exit.");
            Console.ReadLine();
        

            /**//*RemotingConfiguration.RegisterWellKnownServiceType(typeof(Distribution_Framework.InfoCenter), "Broadcast", WellKnownObjectMode.Singleton);
            HttpChannel myChannel = new HttpChannel(8011);
            ChannelServices.RegisterChannel(myChannel);

            IServerChannelSink sc = myChannel.ChannelSinkChain;
            while (sc != null)
            {

                {

            }
            Console.WriteLine("Server is running, Press Enter key to exit.");
            Console.ReadLine();

        }
    }
}

Annoncer:

using  System;
using  System.Timers;
using  System.Runtime.Remoting;

            Announcer announcer = new Announcer();
            announcer.Run();
            Console.WriteLine("The announcer has been started.");
            Console.ReadLine();
        }

            {
                Console.WriteLine(ex.ToString());
                Console.ReadLine();

            Console.WriteLine("Send Message:" + msg);
            infoCenter.Broadcasting(msg.ToString());
        }
    }
}

客户端：

using  System;
using  System.Runtime.Remoting;
using  System.Runtime.Remoting.Channels;
using  System.Runtime.Remoting.Channels.Http;
using  System.Collections;
using  System.Runtime.Serialization.Formatters;

        public Receiver()
        {
        }

        public override object InitializeLifetimeService() 
        {
            return null;
        }

        public void Run()
        {
            try
            {
                //RemotingConfiguration.Configure(@"F:\Broadcast\Receiver\Receiver\Receiver.exe.config");
                HttpChannel channel = new HttpChannel();
                ChannelServices.RegisterChannel(channel);
                RemotingServices.Connect(typeof(InfoCenter),"http://localhost:8011/BroadCaseter");
                infoCenter = new InfoCenter();
                //订阅信息
                infoCenter.Broadcaster += new BroadcastEventHandler(this.BroadcastReceiver);
                //infoCenter.Broadcasting("hello");
                Console.WriteLine("Ready to Recieve Message");
                Console.ReadLine();

                Console.ReadLine();
            }
            //取消订阅
            //infoCenter.Broadcaster -= new BroadcastEventHandler(this.BroadcastReceiver);
        }

        public void BroadcastReceiver(object sender, BroadcastEventArgs args)
        {
            Console.WriteLine("Received:" + args.Message);//打印接收信息
        }

        public static void Main()
        {
            Receiver receiver = new Receiver();
            receiver.Run();
        }
    }
}

在客户端如果用配置文件就报错，说<channels>附进有错误。
客户端配置文件：

<? xml version = " 1.0 "  encoding = " utf-8 "   ?>
< configuration >
    < system.runtime.remoting >
       < application >
          < client >
             < client url = " http://localhost:8011/BroadCaster " >
                 < activated type = " Distribution_Framework.InfoCenter, InfoCenter " />
             </ client >
          < channels >
             < channel  ref = " http "  port = " 0 " />
                 < serverProviders >
                   < provider  ref = " binary "  typeFilterLevel = " Full " />
                 </ serverProviders >
          </ channels >
       </ application >
    </ system.runtime.remoting >
