Questions D'Injection De Dépendance SignalR +

J'utilise SignalR dans mon application MVC3, et puisque j'ai implémenté L'Injection de dépendance StructureMap sur mes contrôleurs, je voudrais faire la même chose dans mon hub, mais je n'arrive pas à le faire fonctionner.

Dites-moi ce qui ne va pas avec mes codes ci-dessous:

SignalRSmDependencyResolver.cs

public class SignalRSmDependencyResolver : DefaultDependencyResolver
{
    private IContainer _container;

    public SignalRSmDependencyResolver(IContainer container)
    {
        _container = container;
    }

    public override object GetService(Type serviceType)
    {
        object service = null;
        if (!serviceType.IsAbstract && !serviceType.IsInterface && serviceType.IsClass)
        {
            // Concrete type resolution
            service = _container.GetInstance(serviceType);
        }
        else
        {
            // Other type resolution with base fallback
            service = _container.TryGetInstance(serviceType) ?? base.GetService(serviceType);
        }
        return service;
    }

    public override IEnumerable<object> GetServices(Type serviceType)
    {
        var objects = _container.GetAllInstances(serviceType).Cast<object>();
        objects.Concat(base.GetServices(serviceType));
        return objects;
    }
}

SignalRExtensionsRegistry.cs

public class SignalRExtensionsRegistry : Registry
{
    public SignalRExtensionsRegistry()
    {
        For<IDependencyResolver>().Add<SignalRSmDependencyResolver>();
    }
}

Cio.cs

public static class IoC {
    public static IContainer Initialize() {

        var container = BootStrapper.Initialize();

        container.Configure(x =>
        {
            x.For<IControllerActivator>().Singleton().Use<StructureMapControllerActivator>();
        });

        return container;
    }
}

public class StructureMapControllerActivator : IControllerActivator {
    public StructureMapControllerActivator(IContainer container) {
        _container = container;
    }

    private IContainer _container;

    public IController Create(RequestContext requestContext, Type controllerType) {
        IController controller = DependencyResolver.Current.GetService(controllerType) as IController;
        return controller;
    }
}

AppStart_Structuremap.cs

[assembly: WebActivator.PreApplicationStartMethod(typeof(StoreUI.AppStart_Structuremap), "Start")]

namespace MyNameSpace {
public static class AppStart_Structuremap {
    public static void Start() {
        var container = (IContainer) IoC.Initialize();
        DependencyResolver.SetResolver(new StructureMapDependenceyResolver(container));
        AspNetHost.SetResolver(new StructureMapDependencyResolver(container));            
    }
}
}

NotificationsHub.cs

[HubName("notificationsHub")]
public class NotificationsHub : Hub
{    
    #region Declarations
    private readonly IUserService userService;
    #endregion

    #region Constructor

    public NotificationsHub(IUserService userService)
    {
        this.userService = userService;
    }

    #endregion

    public void updateServer(string message)
    {
        Clients.updateClient(message);
    }
}

Merci
