    一个WCF服务，以tcp绑定host在控制台上，客户端是console时，能够正常获取元数据且能正常调用，但是放到Silverlight中调用时出现“给定关键字不在字典中。”错误，我估计是WCF的配置文件 <serviceMetadata httpGetEnabled="false"/>这里出错，但是不知道怎么改。

    服务代码：

     

     public class Program
 {
  static void Main(string[] args)
  {
   PolicySocketServer StartPolicyServer = new PolicySocketServer();
   Thread th = new Thread(new ThreadStart(StartPolicyServer.StartSocketServer));
   th.IsBackground = true;
   th.Start();

   MyHost.Open();
   System.Console.WriteLine("服务已经启动... 敲任意键停止服务");
   System.Console.ReadLine();
   MyHost.Close();
  }
 }

 public class MyHost
 {
  static ServiceHost host = null;
  public static void Open()
  {
   host = new ServiceHost(typeof(ChatService)); 
   host.Open();
  }
  public static void Close()
  {
   if (host != null && host.State == CommunicationState.Opened)
   {
    host.Close();
   }
   host = null;
  } 
 }
 public class ChatService : IChatService
 {
  private static List<MessageInfo> listMessages = new List<MessageInfo>();

  public void SendMessage(MessageInfo message)
  {
   listMessages.Add(message);
  }

  public List<MessageInfo> GetMessages(string userName, string partnerName)
  {
   var list = listMessages.Where(m => m.PartnerName == userName && m.UserName == partnerName).ToList();
   listMessages.RemoveAll(m => m.PartnerName == userName && m.UserName == partnerName);
   return list;
  }
 }

 [ServiceContract]
 public interface IChatService
 {
  [OperationContract]
  void SendMessage(MessageInfo message);

  [OperationContract]
  List<MessageInfo> GetMessages(string userName, string partnerName);
 }

     

    app.config配置

     

     <system.serviceModel>
 <services>  
  <service behaviorConfiguration="Server.ChatServiceBehavior" name="Server.ChatService">
  <host>
   <baseAddresses>
   <add baseAddress="net.tcp://localhost:4503/"/>
   </baseAddresses>
  </host>
  <endpoint address="ChatService" binding="netTcpBinding" contract="Server.IChatService"></endpoint>
  <endpoint address="ChatService/mex" binding="mexTcpBinding" contract="IMetadataExchange" ></endpoint>
  </service>  
 </services> 
 
 <behaviors>
  <serviceBehaviors>
  <behavior name="Server.ChatServiceBehavior">
   <serviceMetadata httpGetEnabled="false"/>
   <serviceDebug includeExceptionDetailInFaults="false"/>
  </behavior>
  </serviceBehaviors>
 </behaviors>
 
 </system.serviceModel>

    在SL端引用的地址是net.tcp://localhost:4503/chatservice/mex，引用时没有出错，但是SL端的配置文件ServiceReferences.ClientConfig中没有数据，

    而且在运行SL时，

    ChatService.ChatServiceClient proxy = new ChatService.ChatServiceClient();

    出现“给定关键字不在字典中”的异常提示
