ASP.net 4.6 MVC 5 Autofac Object per session

Question

In my ASP.net MVC application, I want to set a value for an object that should be "exported" per session. I tried like this:

The object I want:

    public class Core : ICore {

    public Core() {
        UserSession = new UserSession();
    }

    public UserSession UserSession { get; set; }
}

global.asax:

protected void Application_Start() {

        var builder = new ContainerBuilder();
        //register ICore
        builder.RegisterType<Core.Core>().As<ICore>().InstancePerLifetimeScope();
        builder.RegisterControllers(typeof (MvcApplication).Assembly);
        builder.RegisterFilterProvider();
        var container = builder.Build();
        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

        BundleConfig.RegisterBundles(BundleTable.Bundles);

        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);
    }

The place where I set the value for the object (UserController):

public class UserController : BaseController {
    private readonly ICore _core;
    private readonly IUserDomain _userDomain;

    public UserController(ICore core, IUserDomain userDomain) {
        _core = core;
        _userDomain = userDomain;
    }

    [HttpPost]
    [AllowAnonymous]
    public ActionResult Login(LoginForm form) {

        if (ModelState.IsValid) {
            var user = _userDomain.GetByName(form.Username);
            if (user != null) {
                // Set Value
                _core.UserSession.CurrentUser = user;

                return RedirectToAction("Index", "Home");
            }
        }
        return View(form);
    }
}

Places where I need this session object

1st in the same application: (Here, ICore is not null, but CurrentUser, which I installed earlier in the controller, is null)

    public class ClaimsAuthorize : AuthorizeAttribute {

    public ICore Core { get; set; }

    protected override bool AuthorizeCore(HttpContextBase httpContext) {
        //Here is CurrentUser null
        var currentUser = Core.UserSession.CurrentUser;
        return currentUser != null;
    }
}

2nd in another project (SQL Context):

public class BaseContext <TModel> where TModel : BaseModel {
    protected readonly ICore Core;
    protected NHibernateSession NHibernateSession;

    public BaseContext(ICore core) {
        Core = core;
    }

    public virtual bool Save(TModel model) {
        if (Core.UserSession.CurrentUser == null) {
            return false;
        }
        model.CreatedBy = Core.UserSession.CurrentUser.Id;
        model.CreatedAt = DateTime.Now;
        using (var session = NHibernateSession.SessionFactory.OpenSession()) {
            using (var transaction = session.BeginTransaction()) {
                session.Save(model);
                transaction.Commit();
            }
        }
        return true;
    }
}

    public class PageContext : BaseContext<Page>, IPageContext {

    public PageContext(ICore core, NHibernateSession nHibernateSession) : base(core) {
        NHibernateSession = nHibernateSession;
    }
}

In your global.asax you can register ICoreas follows:

builder.Register(c =>
{
    if (HttpContext.Current == null)
    {
        throw new Exception("no httpcontext available");
    }

    ICore core = HttpContext.Current.Session["ICore"] as ICore;
    if (core == null)
    {
        core = new Core();
        HttpContext.Current.Session["ICore"] = core;
    }

    return core;
}).As<ICore>();

, Autofac ICore, .
