无法将 VS 2010 中的服务引用添加到 net.tcp 端点

Question

我有一个服务正在运行（好吧，它不会崩溃），但是当我尝试向它添加服务引用时，我不断得到：

元数据包含无法解析的引用：“net.tcp://localhost:55555/mex”。 元数据包含无法解析的引用：“net.tcp://localhost:55555/mex”。 如果在当前解决方案中定义了服务，请尝试构建解决方案并再次添加服务引用。

我的配置文件的相关部分是：

    <netTcpBinding>
 <binding name="ReliableDuplexBinding" closeTimeout="00:00:10"
     openTimeout="00:00:10" receiveTimeout="00:00:30" sendTimeout="00:00:15"
     maxBufferPoolSize="1048576" maxBufferSize="262144" maxReceivedMessageSize="262144">
   <readerQuotas maxDepth="33" maxStringContentLength="100000" maxArrayLength="131072"
      maxBytesPerRead="262144" maxNameTableCharCount="54000" />
   <reliableSession inactivityTimeout="05:00:00" enabled="true" />
   <security mode="None">
    <transport>
     <extendedProtectionPolicy policyEnforcement="Never" />
    </transport>
   </security>
 </binding>
</netTcpBinding>
  <behaviors>
   <serviceBehaviors>
    <behavior name="DefaultServiceBehavior">
     <serviceMetadata httpGetEnabled="false" />
     <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
   </serviceBehaviors>
  </behaviors>
<services>
   <service behaviorConfiguration="DefaultServiceBehavior" name="Cad.Server.RccInboxService">
    <endpoint address="RccInterface" binding="netTcpBinding" bindingConfiguration="ReliableDuplexBinding"
     name="Cad.Server.RccInboxService" contract="Cad.Net.Wcf.Contracts.IRccUserInterface" />
    <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" name="Cad.Server.mex" />
    <host>
     <baseAddresses>
      <add baseAddress="net.tcp://localhost:55555" />
     </baseAddresses>
     <timeouts closeTimeout="00:01:00" />
    </host>
   </service>
  </services>

该服务是自托管的，下面的代码似乎可以工作，但我无法达到创建服务引用的地步：

Public Sub StartServiceHost()
   'Publish the Wcf Service endpoint.
   Try
    shRccUserInterface = New ServiceHost(Me._RccInboxService)
    AddHandler shRccUserInterface.Faulted, AddressOf OnChannelFaulted
    AddHandler shRccUserInterface.Closed, AddressOf OnChannelClosed
    AddHandler shRccUserInterface.Opened, AddressOf OnChannelOpened
    AddHandler shRccUserInterface.Opening, AddressOf OnChannelOpening
    AddHandler shRccUserInterface.UnknownMessageReceived, AddressOf OnUnknownMessageReceived

    Me.bndRccUserInterface = New NetTcpBinding("ReliableDuplexBinding")
    Dim ep As Description.ServiceEndpoint
    With shRccUserInterface
     ep = .AddServiceEndpoint(GetType(Cad.Net.Wcf.Contracts.IRccUserInterface), bndRccUserInterface, String.Empty)
     RaiseEvent ShowUserMessageEvent(Me, "Opening Endpoint: " & ep.Address.ToString, UtaCommon.Interfaces.StatusListEntryType.Information)
     .Open()
    End With
    Me.blnServiceHostOpen = True
    RaiseEvent ServiceHostOpenEvent(Me)
   Catch exWcf As Exception
    log.Write_Error("RccGuiComm", "StartServiceHost()", exWcf)
    RaiseEvent SendUtaEmailEvent("Wcf Problem", exWcf.ToString, System.Net.Mail.MailPriority.High)
   End Try
  End Sub

服务必须是自托管的。我已经为此奋斗了一段时间。如果有人能提供帮助，我将不胜感激。

最好的，

您可以使用 http mex 端点，即使您的主要端点是 nettcp。

确保您拥有：

<serviceMetadata httpGetEnabled="true" />
