无法使用netTcpBinding将WCF服务引用添加到客户端项目

我有一个使用NetTcpBinding的WCF服务，我想将其托管在WPF应用程序中。该服务似乎正常启动，但是当我尝试在Visual Studio中使用“添加服务引用”获取其元数据时，出现此异常：

The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8000/Mandrake/mex'.

我的服务项目的App.config文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
  <compilation debug="true" />
</system.web>
<system.serviceModel>
  <services>
    <service name="Mandrake.Service.OTAwareService">
      <endpoint address="OTService" binding="netTcpBinding" contract="Mandrake.Service.IOTAwareService">
        <identity>
          <dns value="localhost" />
        </identity>
      </endpoint>
      <endpoint name="MEX" address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
      <host>
        <baseAddresses>
          <add baseAddress="net.tcp://localhost:8000/Mandrake/" />
        </baseAddresses>
      </host>
    </service>
  </services>
  <behaviors>
    <serviceBehaviors>
      <behavior>
        <serviceMetadata/>
        <serviceDebug includeExceptionDetailInFaults="False" />
      </behavior>
    </serviceBehaviors>
  </behaviors>
</system.serviceModel>

</configuration>

以及托管应用程序中的代码：

Uri baseAddress = new Uri("net.tcp://localhost:8000/Mandrake");
ServiceHost host = new ServiceHost(typeof(OTAwareService), baseAddress);

try
{
    host.AddServiceEndpoint(typeof(IOTAwareService), new NetTcpBinding(), "OTService");

}
catch (CommunicationException e)
{
    Console.WriteLine(e.Message);
    host.Abort();
}

我发现该问题的解决方案主要是将'serviceMetaData'添加到服务配置中或提供mex端点。你能建议点什么吗？

编辑：

最终配置：

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="NewBehavior0">
      <serviceMetadata />
      <serviceDebug includeExceptionDetailInFaults="True" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service name="Mandrake.Service.OTAwareService" behaviorConfiguration="NewBehavior0">
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:8036/OTService"/>
      </baseAddresses>
    </host>

    <endpoint address="" binding="netTcpBinding" name="TcpEndpoint" contract="Mandrake.Service.IOTAwareService" />
    <endpoint address="mex" binding="mexTcpBinding" name="MetadataEndpoint" contract="IMetadataExchange" />

  </service>
</services>
</system.serviceModel>

托管应用程序：

host = new ServiceHost(typeof(OTAwareService));
host.Open();
