防火墙规则应用同一子网计算机,在关闭防火墙的同一子网上的两台计算机之间，WCF发现不起作用...

这个简单的WCF发现示例适用于单个计算机，但是当客户端和服务器在同一子网中没有防火墙的不同计算机上运行时，它不起作用 . 我错过了什么？

using System;

using System.Linq;

using System.Net;

using System.Net.Sockets;

using System.ServiceModel;

using System.ServiceModel.Discovery;

namespace WCFDiscovery

{

class Program

{

static void Main(string[] args)

{

try { if (args.Length > 0) StartClient(); else StartServer(); }

catch (Exception ex) { Console.WriteLine(ex); }

finally { Console.WriteLine("press enter to quit..."); Console.ReadLine(); }

}

private static void StartServer()

{

var ipAddress = Dns.GetHostAddresses(Dns.GetHostName()).First(ip => ip.AddressFamily == AddressFamily.InterNetwork);

var address = new Uri(string.Format("net.tcp://{0}:3702", ipAddress));

var host = new ServiceHost(typeof(Service), address);

host.AddServiceEndpoint(typeof(IService), new NetTcpBinding(), address);

host.Description.Behaviors.Add(new ServiceDiscoveryBehavior());

host.AddServiceEndpoint(new UdpDiscoveryEndpoint());

host.Open();

Console.WriteLine("Started on {0}", address);

}

private static void StartClient()

{

var dc = new DiscoveryClient(new UdpDiscoveryEndpoint());

Console.WriteLine("Searching for service...");

var findResponse = dc.Find(new FindCriteria(typeof(IService)));

var response = ChannelFactory.CreateChannel(new NetTcpBinding(), findResponse.Endpoints[0].Address).Add(1, 2);

Console.WriteLine("Service response: {0}", response);

}

}

[ServiceContract] interface IService { [OperationContract] int Add(int x, int y); }

class Service : IService { public int Add(int x, int y) { return x + y; } }

}
