我有一个服务，那个principal我想是双工的，但是，对于一些操作，我需要使用流传输模式，所以我想要两个合约，一个是通用合约，让我与数据库并在我需要时从服务向客户端发送消息，以及与文件交互、保存文件并将文件获取到数据库的其他合同。

我需要这两个合同，因为 tcp 绑定与双工不兼容。

该服务托管在 WPF 应用程序中，配置文件如下：

<system.serviceModel>
    <services>          
      <service name="GTS.CMMS.Service.Service" behaviorConfiguration="behaviorConfig">
        <host>
          <baseAddresses>

            <add baseAddress="net.tcp://localhost:7997/CMMSHost"/>
            <add baseAddress="http://localhost:7998/CMMSHost"/>
          </baseAddresses>
        </host>   


        <endpoint address="/ServiceCore"
                  binding="netTcpBinding"
                  bindingConfiguration="tcpBinding"
                  name="ServiceCore"
                  contract="GTS.CMMS.Service.IService">
          <!--<identity>
            <dns value="localhost" />
          </identity>-->
        </endpoint>


        <endpoint address="/ServiceDocumentos"
                  binding="netTcpBinding"
                  bindingConfiguration="tcpBindingDocumentos"
                  name="ServiceDocumentos"
                  contract="GTS.CMMS.Service.IServiceDocumentos">
          <!--<identity>
            <dns value="localhost" />
          </identity>-->
        </endpoint>


        <endpoint contract="IMetadataExchange" binding="mexTcpBinding" address="net.tcp://localhost:5000/mex" />
      </service>      
    </services>


    <!--El behavior son datos de configuración del servicio que no forman parte del endpoint.

    <behaviors>
      <serviceBehaviors>

          <!--Necesario para poder mandar excepciones desde el servicio hasta el cliente.-->
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceThrottling maxConcurrentCalls="100" maxConcurrentSessions="100" />
        </behavior>


        <behavior name="behaviorConfigDocumentos">
          <!--<serviceMetadata httpGetEnabled="true" />-->
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
          <!--Necesario para poder mandar excepciones desde el servicio hasta el cliente.-->
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceThrottling maxConcurrentCalls="100" maxConcurrentSessions="100" />
          <serviceMetadata/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

                       transferMode="Buffered" closeTimeout="00:00:10"
                       openTimeout="00:00:10" receiveTimeout="00:20:00"
                       sendTimeout="00:01:00" maxConnections="100">

          <reliableSession enabled="true" inactivityTimeout="00:20:00" />
        </binding>


        <binding name="tcpBindingDocumentos" maxBufferSize="67108864"
                      maxReceivedMessageSize="67108864" maxBufferPoolSize="67108864"
                       transferMode="Streamed" closeTimeout="00:00:10"
                       openTimeout="00:00:10" receiveTimeout="00:20:00"
                       sendTimeout="00:01:00" maxConnections="100">
          <security mode="None"/>
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
              maxArrayLength="2147483647" maxBytesPerRead="2147483647"
              maxNameTableCharCount="2147483647"/>
          <reliableSession enabled="true" inactivityTimeout="00:20:00" />
        </binding>
      </netTcpBinding>

    </bindings>
  </system.serviceModel>

要检查是否一切正常，我会访问 Internet Explorer 并访问：

http://localhost:7998/CMMSHost

如果我有两个端点，则找不到页面，但如果我评论第二个端点，则找到“/ServiceDocumentos”页面，我可以使用 svcutil 创建代理。

如何配置多个端点？

谢谢。
