里面有两个cs文件，

SocketPolicy.cs 

Code [http://www.xueit.com] 
1     public static class SocketPolicy
2     {
3         public const string Policy = @"
4             <?xml version=""1.0"" encoding =""utf-8""?>
5             <access-policy>
6               <cross-domain-access>
7                 <policy>
8                   <allow-from>
9                     <domain uri=""*"" />
10                   </allow-from>
11                   <grant-to>
12                     <socket-resource port=""4502-4530"" protocol=""tcp"" />
13                   </grant-to>
14                 </policy>
15               </cross-domain-access>
16             </access-policy>
17             ";
18     }

还有一个文件，内容太长，这里就不给代码了，大家可以自己新建一下看看。

拷到你的项目中就可以，不用手写。

由于代码很多这里我就不全写出来了，只把需要注意的地方告诉大家，我会把整个的demo提供给大家下载。

App.config 做为这个宿主程序的灵魂，这个破config整得我都快疯掉了。这里面就是普通的wcf配置，请注意一下我写注释的地方就可以。

Code [http://www.xueit.com]

11         <bindings>
12             <customBinding> <!--注意，这里只能使用自定义的绑定，应为Silverlight4测试版并不完全技术net.tcp-->
13                 <binding name="WebChat.Service.ChatService1">
14                     <binaryMessageEncoding></binaryMessageEncoding>

宿主程序启动

Code [http://www.xueit.com] 
1     class Program
2     {
3         static void Main(string[] args)
4         {
5             PolicyServer ps = new PolicyServer(SocketPolicy.Policy);    //启动943策略文件监听端口
6 
7             ServiceHost host = new ServiceHost(typeof(WebChat.Service.ChatService)); 
8             Console.WriteLine(); 
9             host.Open();
10             System.Console.WriteLine("聊天室服务器开始监听...");
11             System.Console.WriteLine("按 ENTER 停止服务器监听...");
12             System.Console.ReadLine();
13             host.Abort();
14             host.Close();
15             ps.Close();
16         }  
17     }
