wcf - 我的 WCF 实现类引用未显示在 Windows 服务中

Question

我的 Windows 服务现在显示了我的 WCF 实现类。因此，当我启动我的服务时，它给了我“ServiceHost 仅支持类服务类型”的错误。这是我的代码：

        try
        {

            Console.WriteLine("Testing 1");
            WCFEmailEventLog.WriteEntry("My service started"); 
            System.Diagnostics.Debugger.Break();
            // Create a ServiceHost 
            // provide the base address.
            serviceHost = new ServiceHost(typeof(TestBulkEmailService.BulkEmailService), new Uri("http://localhost/TestBulkEmailService/TestBulkEmailService.svc") );

            WCFEmailEventLog.WriteEntry("After Service host "); 
            // Open the ServiceHostBase to create listeners and start 
            // listening for messages.
            serviceHost.Open();

在上面的代码中，typeOf(TestBulkEmailService.BulkEmailService) 不显示实现类 BulkEmailService，只显示我的 WCF 合同 IBulkEmailService。

我究竟做错了什么？

这是我的 app.config 文件：

        <services>
    <service name="WW.Common.Service.Impl.BulkEmailService" behaviorConfiguration="BulkEmailService">
      <host>
        <baseAddresses>
          <add baseAddress="http://localhost/TestBulkEmailService/TestBulkEmailService.svc"/>
        </baseAddresses>
      </host>
      <endpoint address="BulkEmailService" binding="basicHttpBinding" contract="TestBulkEmailService.IBulkEmailService" />
      <endpoint address="mex" binding="basicHttpBinding" name="mexEndpoint" contract="IMetadataExchange" />
    </service>
  </services>
<behaviors>
  <serviceBehaviors>
    <behavior name="BulkEmailService">
      <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>
      <serviceMetadata httpGetEnabled="true" />
      <serviceSecurityAudit auditLogLocation="Application"
         suppressAuditFailure="true"
         serviceAuthorizationAuditLevel="Success"
         messageAuthenticationAuditLevel="Success" />
    </behavior>
  </serviceBehaviors>
</behaviors>

这是我的 .svc 文件，它托管在 IIS 中，在使用客户端应用程序时运行良好。

 <%@ ServiceHost Language="C#" Debug="true" Service="WW.Common.Service.Impl.BulkEmailService" %>

这是我用作服务参考并将其命名为 TestBulkEmailService 的 WCF 服务的实现和合同。
