c# - WCF 多重绑定(bind)

Question

当我尝试多个端点时出现以下错误..

System.ServiceModel.AddressAlreadyInUseException: The TransportManager failed to listen on the supplied URI using the NetTcpPortSharing service: the service failed to listen.
   at System.ServiceModel.Channels.SharedConnectionListener.SharedListenerProxy.Register()
   at System.ServiceModel.Channels.SharedConnectionListener.SharedListenerProxy.Open(Boolean isReconnecting)

这是我的 App.Config 内容

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
  <system.serviceModel>
    <bindings>

          </security>
        </binding>
      </netTcpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="WcfServiceLibrary1.Service1Behavior"
        name="WcfServiceLibrary1.Service1">

          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <endpoint address="Service" binding="netTcpBinding" bindingConfiguration="tcpBinding"
          name="testTcp" contract="WcfServiceLibrary1.IService1" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/" />
            <add baseAddress="net.tcp://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service" />

          </baseAddresses>

        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WcfServiceLibrary1.Service1Behavior">
          <!-- To avoid disclosing metadata information,

          <serviceMetadata httpGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes,

        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

如果有人能在我错的地方指导我，那就太好了。

在 App.Config 和 Windows Service 中都启用了 Net TCP 端口共享服务。这是我所能检查的。

Answer 1

您不能在两个不同的绑定(bind)之间共享完全相同的端口，根据您在上面发布的配置，您目前正在这样做。您需要将 wsHttp 绑定(bind)在与 net.tcp 绑定(bind)不同的端口上。 net.tcp 端口共享的目的是允许多个进程将同一端口用于多个 net.tcp 绑定(bind)...而不是跨多个不同的绑定(bind)和协议(protocol)共享一个端口。

要成功利用 WCF net.tcp 端口共享，您需要启动“Net.Tcp 端口共享服务”(请注意，它在名称中明确说明了 Net.Tcp)。您可能还想将它设置为自动启动，这样您就不必在重新启动时继续启动它。一旦启动了端口共享windows服务，你就可以在同一个进程中，跨多个进程，在同一台物理机上为任何net.tcp绑定(bind)共享一个端口。每个需要共享端口的 net.tcp 绑定(bind)都需要将 portSharingEnabled 属性设置为 true。如果您执行上述操作，那么您应该能够在任何进程中为启用了端口共享的任何 net.tcp 端点重用相同的端口。

这将不允许您与任何 wsHttp 绑定(bind)、basicHttp 绑定(bind)、任何 MSMQ 绑定(bind)或任何第三方绑定(bind)共享同一端口。这是 WCF 自带的 netTcpBinding 特有的功能。
