Asp net Identity, calling AccountController from HomeController and trouble with UserMenager

So I have successfully implemented Account controller and various methods that come with it. I have one specific method that returns AppUser (current user) 

public AppUser GetCurrentUser(){
       AppUser user = UserMenager.FindById(User.Identity.GetUserId());
       return user; }.

Now I don't want to have instance of UserMenager in all of my controllers (or should I?), so in my HomeController I need to render a partial view based on is user logged in or not, so I call this method

public ActionResult RightNavigation()
        {   
            // account is instance of AccountController
            AppUser user = account.GetCurrentUser();

            if (user == null)
            {
                return PartialView("NavWhenNotLogged");
            }
            else
            {
                return PartialView("NavWhenLogged",user);
            }
        }

Problem is, I am getting NullException for the UserMenager instance in Account Controller : 

private AppUserMenager UserMenager
        {
            get
            {
                return HttpContext.GetOwinContext().GetUserManager<AppUserMenager>();
            }
        }

Now I assume this is not the right way to 'share' UserMenager in different Controllers so If you could just give me 'the' way to this this.

In summary : I have Account controller that has various methods about users, etc. When I try to use one of those methods that relies on UserMenager, I get Null Exception for UserMenager.

In your Startup class you need to call the following line inside Configuration method, which puts the instance of ApplicationUserManager into OwinContext for every request.

    public void Configuration(IAppBuilder app)
    {
        app.CreatePerOwinContext<UserManager>(UserManager.Create);
    }

UserManager.Create() is a static method returns the instance.

Don't call controller from another controller. To get the UserManager you can do it in any controller's action:

    var userManager = HttpContext.GetOwinContext().GetUserManager<UserManager>();

Request.IsAuthenticated

In the default MVC5 project there is sample check for if user is logged in in the _LoginPartial.cshtml.
