WCF net.tcp 连接总是失败

Question

我尝试使用 net.tcp 绑定(bind)设置用于测试的服务。我还设置了一个 http 端点。配置如下:

  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="Inbound_REST">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="InboundHttpConfiguration">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="InboundTcpConfiguration">
          <serviceMetadata httpGetEnabled="false" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="InboundTcpConfiguration" name="Inbound">
          <endpoint address="" binding="netTcpBinding" contract="IContract">
            <identity>
              <dns value="localhost"/>
            </identity>
          </endpoint>
          <host>
            <baseAddresses>
              <add baseAddress="net.tcp://localhost:6969/Inbound" />
            </baseAddresses>
          </host>
        </service>
    </services>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <client>
      <endpoint name="httpEndPoint" address="http://localhost:1568/Inbound.svc" binding="basicHttpBinding" contract="IContract" />
       <endpoint name="tcpEndPoint" address="net.tcp://localhost:6969/Inbound" binding="netTcpBinding" contract="IContract" />
    </client>
    <bindings>
      <basicHttpBinding>
        <binding name="httpbind">
          <security mode="Transport">
            <transport clientCredentialType="None"/>
          </security>
        </binding>
      </basicHttpBinding>
      <netTcpBinding>
        <binding name="tcpbind">
          <security mode="Transport">
            <transport clientCredentialType="None" />
          </security>
        </binding>
      </netTcpBinding>
    </bindings>
  </system.serviceModel>

当我尝试使用 net.tcp 绑定(bind)使用服务时，它总是返回错误:

无法连接到 net.tcp://localhost:6969/Inbound。连接尝试持续了 00:00:00.9531494 的时间跨度。 TCP 错误代码 10061:无法建立连接，因为目标机器主动拒绝 127.0.0.1:6969。

顺便说一句，http 绑定(bind)工作正常。我认为这可能是一些机器配置，但无法找到根本原因。

如果您尝试通过 Visual Studio 运行 WCF 服务，则不支持 netTcpBinding。对不起!
