StructureMap Setter Injection not setting property

Question

I am trying to setup setter/property injection for my MVC project using StructureMap, but I can't seem to get it to set the properties. I am well aware that Constructor injection is the recommended practice, but I have a strict requirement that requires we do it using setter injection, so please hold the comments attempting to tell me otherwise.

I have the normal boilerplate setup code such as the following in my Global.asax

ControllerBuilder.Current.SetControllerFactory(new TestControllerFactory());

ObjectFactory.Initialize(x => {
            x.For<IPaymentService>().Use<PaymentService>();
            x.ForConcreteType<HomeController>().Configure.Setter<IPaymentService>(y => y.PaymentService).IsTheDefault();
            x.SetAllProperties(y =>
            {
                y.OfType<IPaymentService>();
            });

        });

My TestControllerFactory looks like the following:

public class TestControllerFactory:System.Web.Mvc.DefaultControllerFactory
{
    protected  IController GetControllerInstance(Type controllerType)
    {
        if (controllerType == null)
            throw new ArgumentNullException("controllerType");
        return ObjectFactory.GetInstance(controllerType) as IController ;
    }
}

I have the following Service/Implementation class pair

public interface IPaymentService
{

}

public class PaymentService:IPaymentService
{

}

And finally, I have my controller that will have the property that needs to have the concrete payment service implementation injected into it:

public class HomeController:Controller { public IPaymentService Service {get;set;}

 public ActionResult Index(){
        var test = Service... //Service is Null
 }

}

Shown above, the property remains null when I debug.

Additionally, I have tried using the [SetterProperty] just to see if it worked(I have no intention of coupling my controllers with those attributes), and it still didnt work.

I am not sure if I need to do something else, or what the problem might be. I have been using constructor injection with StructureMap for quite awhile.

Try dropping this line:

x.ForConcreteType<HomeController>().Configure
  .Setter<IPaymentService>(y => y.PaymentService).IsTheDefault();

It shouldn't be necessary.

Given the following controller:

public class HomeController : Controller
{
    public IMsgService Service { get; set; }

    public ActionResult Index()
    {
        return Content(Service.GetMessage());
    }
}

This was all that was required to configure StructureMap to set the property:

ObjectFactory.Initialize(cfg =>
{
    cfg.For<IMsgService>().Use<MyMsgService>();

    cfg.SetAllProperties(prop =>
    {
        prop.OfType<IMsgService>();
    });
});

ControllerBuilder.Current.SetControllerFactory(new StructureMapControllerFactory());
