wcf双工服务问题

我是新来的WCF，我尝试创建一个双工服务，我得到一个异常，这个问题“HTTP无法注册URL http://+:80/Temporary_Listen_Addresses/42be316a-0c86-4678-a61a-fc6a5fd10599/，因为TCP端口80正在被另一个应用程序使用。我会在这里发布整个代码，我希望你有时间去看看。我正在使用Windows XP。wcf双工服务问题

    { 
     static void Main(string[] args) 
     { 
      ServiceHost host = new ServiceHost(typeof(RandomService)); 
      host.Open(); 
      Console.WriteLine("Service is running, press <ENTER> to stop it"); 
      Console.ReadLine(); 
      host.Close(); 
     } 
    } 
    public class RandomService : IRandomService 
    { 
     public void GenerateRandomNumber(int limit) 
     { 
      Random r = new Random(); 
      int genInteger = r.Next(limit); 
      Thread.Sleep(3000); 
      IRandomCallback callback = OperationContext.Current.GetCallbackChannel<IRandomCallback>(); 
      callback.ShowRandomNumber(genInteger); 
     } 
    } 
    public interface IRandomCallback 
    { 
     [OperationContract(IsOneWay = true)] 
     void ShowRandomNumber(int ranomNumber); 
    } 
    [ServiceContract(CallbackContract = typeof(IRandomCallback))] 
    public interface IRandomService 
    { 
     [OperationContract(IsOneWay = true)]
