无法使WCFExtras与WCF服务一起工作

我收到一个错误，无法提取服务的元数据。当我查看WCFExtras示例时，它看起来都很好，并且该示例运行良好。唯一的区别是我的WCF服务是.NET4.0

这就是my web.config的外观：

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>

    <customErrors mode="Off" />

  </system.web>

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
    <validation validateIntegratedModeConfiguration="false" />
    <directoryBrowse enabled="true" />
  </system.webServer>

  <system.serviceModel>
    <services>
      <service behaviorConfiguration="CDITecServices.TECServiceHelperBehavior"
               name="CDITecServices.ITECServiceHelper">
        <endpoint address=""
          behaviorConfiguration="CDITecServices.TECServiceHelperEndpointBehavior"
          binding="basicHttpBinding" contract="CDITecServices.ITECServiceHelper"/>
      </service>
    </services>


    <behaviors>
      <endpointBehaviors>
        <behavior name="CDITecServices.TECServiceHelperEndpointBehavior">
          <wsdlExtensions singleFile="True"/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>

                        httpHelpPageEnabled="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <extensions>
      <behaviorExtensions>
        <!-- Declare that we have an extension called WSDL Extras-->
        <add name="wsdlExtensions"
             type="WCFExtras.Wsdl.WsdlExtensionsConfig, WCFExtras, Version=1.0.0.0,
                   Culture=neutral, PublicKeyToken=null"/>
      </behaviorExtensions>
    </extensions>

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
                               multipleSiteBindingsEnabled="true"/> 
  </system.serviceModel>


</configuration>

        [OperationContract]
        void DownloadDataFile(string OrderTicketId, string Username,
                              string Password, string UserDatabase);

        [OperationContract]
        List<string> GetRecordsFromFile(string OrderTicketId, ref long StartIndex);

        // TODO: Add your service operations here
    }
}

这就是我的界面的样子：

字符串密码，字符串用户数据库）；

}
}

将您的服务名称从

CDITecServices.ITECServiceHelper

更新为类名称

CDITecServices.tecservice helper

<service behaviorConfiguration="CDITecServices.TECServiceHelperBehavior" name="CDITecServices.TECServiceHelper">

---

标记上的name属性必须与服务类的名称匹配，包括名称空间。

“无法下拉元数据”-如何“拉动”它？确切的错误是什么？尝试在Visual Studio中运行svc或尝试从Visual Studio创建对服务的引用。如果部署svc，然后尝试浏览它，则会收到消息“此服务的元数据发布当前已禁用”
