我的WCF实现类引用未显示在Windows服务中

Question

我的Windows服务现在正在显示我的WCF实现类。 因此，当我启动我的服务时，它给出了“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Implementation类BulkEmailService，只显示我的WCF Contract IBulkEmailService。

我做错了什么？

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，它已经在IIS中托管，并且在使用客户端应用程序时运行正常。

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

这是我作为服务参考使用的WCF服务的实现和合同，并将其命名为TestBulkEmailService。
