public class HelloWorldServiceFactory : Factory

The factory’s constructor is used to register descriptors and their corresponding component types.

public HelloWorldServiceFactory(){    
    RegisterAsType(ControllerDescriptor, typeof(HelloWorldController));    
    RegisterAsType(HttpServiceDescriptor, typeof(HelloWorldRestService));
}
