My WCF Implementation class reference is not showing up in Windows Service - wcf

Question

My Windows Service is now showing up my WCF Implementation class.
Hence when I start my service it is giving me error of "ServiceHost only supports class service types."
Here's my code:
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();
In the above code the typeOf(TestBulkEmailService.BulkEmailService) does not show the Implementation class BulkEmailService and only shows my WCF Contract IBulkEmailService.
What am I doing wrong?
Here is my app.config file:
<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>
And here is my .svc file which has been hosted in IIS and is running fine when using a client app.
<%# ServiceHost Language="C#" Debug="true" Service="WW.Common.Service.Impl.BulkEmailService" %>
Here's my Implementation and Contract for the WCF Service which I have used as Service reference and have named it as TestBulkEmailService.
