使用netTcp绑定时添加服务引用

Question

我有一个WCF服务,我通过将其接口复制到示例客户端项目来测试.
现在我想通过添加服务引用来正常工作.
该服务托管在Windows托管(使用installUtil)中.
该服务有2个项目 - 外部(接口+数据交换)和内部(实现).
由于某种原因,它没有app.config所以我手动添加了一个:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="ExecutionService" behaviorConfiguration="Default">
        <endpoint name="TCPEndpoint" address="" binding ="netTcpBinding" contract="Externals.IExecutionService"/>
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:3040/ExecutionService"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Default">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

尝试从我的示例客户端添加服务引用会导致以下错误:

Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:3040/ExecutionService/Externals.IExecutionService'.
There was no endpoint listening at net.tcp://localhost:3040/ExecutionService/Externals.IExecutionService that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
If the service is defined in the current solution, try building the solution and adding the service reference again.

我在这里看到app.config中没有必要.
我有点困惑,我是初学者WCF.
一个不错的WPF应用程序如何引用我的服务？我希望服务是windows托管的,我不想和我一起拖动dll.

编辑
我添加了一个元数据端点,我的appconfig现在看起来像这样:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="ExecutionService" behaviorConfiguration="Default">
        <endpoint name="TCPEndpoint" 
                  address="" 
                  binding ="netTcpBinding" 
                  contract="Externals.IExecutionService"/>
        <endpoint address="mex" 
                  binding="maxHttpBinding" 
                  contract="Externals.IExecutionService"/>
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:3040/ExecutionService"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Default">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

我试图通过使用添加服务引用net.tcp://localhost:3040/ExecutionService,net.tcp://localhost:3040/ExecutionService/Externals并net.tcp://localhost:3040/ExecutionService/Externals/IExecutionService和我仍然得到同样的错误.

你需要这样做:

1. maxHttpBinding - > mexTcpBinding - 你不能在net.tcp端点上使用mexHttpBinding(而且它的mex不是max)
2. mex端点的合同必须是IMetadataExchange - 因为您希望通过此端点提供服务元数据
3. httpGetEnabled ="false",因为没有http端点可以从中获取元数据
4. 当我在一个简单的控制台主机中测试解决方案时,我需要将<service>标签中的名称更改为Externals.ExecutionService(但这取决于您实例化服务的方式)

然后,您的服务引用将在以下位置提供:net.tcp://localhost:3040/ExecutionService/mex 作为基址,net.tcp://localhost:3040/ExecutionService并且mex端点的相对地址设置为mex

最终的app.config如下:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
  <service name="Externals.ExecutionService" behaviorConfiguration="Default">
    <endpoint name="TCPEndpoint"
              address=""
              binding ="netTcpBinding"
              contract="Externals.IExecutionService"/>
    <endpoint address="mex"
              binding="mexTcpBinding"
              contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://localhost:3040/ExecutionService"/>
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="Default">
      <serviceMetadata httpGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

为了快速测试配置是否正确,我使用控制台主机应用程序作为服务主机.Program.cs中:

using System;
using System.ServiceModel;

namespace Externals
{
    class Program
    {
        static void Main(string[] args)
        {

            var sh=new ServiceHost(typeof(ExecutionService));
            sh.Open();
            Console.WriteLine("Service running press any key to terminate...");
            Console.ReadKey();
            sh.Close();
        }
    }
}

运行控制台应用程序并尝试通过添加服务引用到您的项目net.tcp://localhost:3040/ExecutionService/mex.
