这真的是窃听我要几个小时。我创建了一个使用TCP绑定的最简单的WCF服务。

This really is bugging me for a couple of hours. I created the simplest WCF service using a TCP binding.

namespace WcfTcpService
{
    public class TestTcpService : ITestTcpService
    {
        public string Hello(string name)
        {
            return "Hello, " + name + "!";
        }
    }
}

namespace WcfTcpService
{
    [ServiceContract]
    public interface ITestTcpService
    {
        [OperationContract]
        string Hello(string name);
    }
}

Web.config文件中有如下内容：

Web.config file has the following section:

  <system.serviceModel>
    <services>
      <service name="WcfTcpService.TestTcpService" behaviorConfiguration="TestServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:808/WcfTcpService.TestTcpService" />
          </baseAddresses>
        </host>
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="tcpBinding" contract="WcfTcpService.ITestTcpService"></endpoint>
        <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange"></endpoint>
      </service>
    </services>
    <bindings>
      <netTcpBinding>
        <binding name="tcpBinding" portSharingEnabled="true">
          <security mode="None"></security>
        </binding>
      </netTcpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="TestServiceBehavior">
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <!--<protocolMapping>
      <add binding="basicHttpsBinding" scheme="https" />
      <add binding="netTcpBinding" scheme="net.tcp" />
    </protocolMapping>-->    
    <!--<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />-->
  </system.serviceModel>

此服务承载于IIS：

现在，尝试添加引用时的net.tcp：//本地主机：808 / WcfTcpService.TestTcpService 从客户端应用程序，我不断收到错误：

Now, when trying to add a reference to net.tcp://localhost:808/WcfTcpService.TestTcpService from a client application, I keep receiving the error:

The URI prefix is not recognized.
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost/WcfTcpService.TestTcpService'.
The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/WcfTcpService.TestTcpService' is unavailable for the protocol of the address.
If the service is defined in the current solution, try building the solution and adding the service reference again.

通过net.tcp服务正在运行，我收到同样的错误与WcfTestClient.exe。我可以成功地运行的http：//localhost/WcfTcpService/TestTcpService.svc

我搜索谷歌，但没有结果出来了。

I've searched google but nothing came up.

谢谢！

推荐答案

在创建使用NetTcpBinding的服务，您要添加在Visual Studio中，你应该使用HTTP地址（httpGetEnabled）服务引用不实际的TCP地址服务侦听。因此，解决办法是设置本地主机/ WcfTcpService / TestTcpService.svc在添加服务引用对话框的URL。

When you create service that uses netTcpBinding and you want to Add service reference in Visual Studio you should use http address (httpGetEnabled) not actual tcp address the service listens on. So the solution was to set localhost/WcfTcpService/TestTcpService.svc as an url in Add service reference dialog.
