WCF TCP端点无法添加服务引用

Question

在我的业余时间里,我一直在和这个人争斗好几个星期,决心不转向这个美妙的社区.但是我的精神被打破了.所以......

我创建了一个WCF服务,并尝试在控制台应用程序中托管它,以便使用TCP端点.

我有一个包含合同和svc文件的项目.我有另一个项目,其中包含一个Console应用程序,它引用了第一个提到的项目.我的控制台应用程序的主要方法如下所示:

using (ServiceHost host = new ServiceHost(typeof(LicenceBucketWireService.LicenceBucketService)))
{
    host.Open();

    foreach (var endpt in host.Description.Endpoints)
    {
        Console.WriteLine("Enpoint address:\t{0}",endpt.Address);
        Console.WriteLine("Enpoint binding:\t{0}",endpt.Binding);
        Console.WriteLine("Enpoint contract:\t{0}\n", endpt.Contract.ContractType.Name);
    }
    Console.ReadLine();
}

直到这一点,一切都是花花公子:

当我尝试将该服务的服务引用添加到将要使用该服务的第3个完全独立的应用程序时,它会出错.当我尝试添加引用时,使用net.tcp:// localhost:49189/LicenceBucketWireService/LicenceBucketService/mex作为发现详细信息的地址,我收到错误:

无法识别URI前缀.元数据包含无法解析的引用:'net.tcp:// localhost:49189/LicenceBucketWireService/LicenceBucketService/mex'.元数据包含无法解析的引用:'net.tcp:// localhost:49189/LicenceBucketWireService/LicenceBucketService/mex'.如果在当前解决方案中定义了服务,请尝试构建解决方案并再次添加服务引用.

执行此任务时,控制台应用程序正在运行.app config包含以下元素:

  <system.serviceModel>
    <services>
      <service name="LicenceBucketWireService.LicenceBucketService">
        <clear />
        <endpoint address="mex" binding="mexTcpBinding" contract="LicenceBucketWireService.ILicenceBucketService"
          listenUriMode="Explicit">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="net.pipe://localhost/licenceBucketService"
          binding="netNamedPipeBinding" bindingConfiguration="" contract="LicenceBucketWireService.ILicenceBucketService" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:49187/LicenceBucketWireService/LicenceBucketService" />
            <add baseAddress="net.tcp://localhost:49189/LicenceBucketWireService/LicenceBucketService" />
          </baseAddresses>
        </host>
      </service>
    </services>    
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="false" />
          <!-- 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>
  </system.serviceModel>

Answer 1

配置文件中的以下代码行:

<endpoint address="mex" binding="mexTcpBinding" contract="LicenceBucketWireService.ILicenceBucketService"
          listenUriMode="Explicit">

应该将合同作为"IMetadataExchange"而不是LicenceBucketWireService.ILicenceBucketService.

那应该解决这个问题.
