OData (WCF Data Service) with Subsonic 3

Question

I am trying to use the WCF data service with Subsonic, but I encountered this error while trying to access my "service.svc". I have 2 projects, one of them is a class library (called "OData"), which has Subsonic t4 templates for generating classes for my table. Another ASP.NET MVC2 project that references the "OData" project.

Then I create a new WCF data service in my ASP.NET MVC project called "service.svc", points to my "TestDB" context created by Subsonic, which I got from the "OData" project. I am adding this attribute to my "service" class for this article: http://theruntime.com/blogs/jaykimble/archive/2008/11/18/quotsubsonicquot-for-services-found-subsonic-3--ado.net -data-services.aspx

This is what my service class looks like:

[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)] 
public class Service : DataService<SymetraGivingDB>
{
   // This method is called only once to initialize service-wide policies.
   public static void InitializeService(DataServiceConfiguration config)
   {
      // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
      // Examples:
      // config.SetEntitySetAccessRule("MyEntityset", EntitySetRights.AllRead);
      // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All);
      config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
      config.SetServiceOperationAccessRule("*", ServiceOperationRights.AllRead);
      config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
   }
}

When I try to access http: //localhost/Service.svc , I get this error:

The request failed
