ASP.NET (C#) Question

MVC 5 Access Claims Identity User Data

I am developing an MVC 5 web application using Entity Framework 5 Database First approach. I am using OWIN for the authentication of Users. Below shows my Login method within my Account Controller.

public ActionResult Login(LoginViewModel model, string returnUrl)
if (ModelState.IsValid)
var user = _AccountService.VerifyPassword(model.UserName, model.Password, false);
if (user != null)
var identity = new ClaimsIdentity(new[] { new Claim(ClaimTypes.Name, model.UserName), }, DefaultAuthenticationTypes.ApplicationCookie, ClaimTypes.Name, ClaimTypes.Role);

identity.AddClaim(new Claim(ClaimTypes.Role, "guest"));
identity.AddClaim(new Claim(ClaimTypes.GivenName, "A Person"));
identity.AddClaim(new Claim(ClaimTypes.Sid, user.userID)); //OK to store userID here?

AuthenticationManager.SignIn(new AuthenticationProperties
IsPersistent = model.RememberMe
}, identity);

return RedirectToAction("Index", "MyDashboard");
ModelState.AddModelError("", "Invalid username or password.");
// If we got this far, something failed, redisplay form
return View(model);

As you can see I'm creating a ClaimsIdentity and adding several claims to it, then passing it to OWIN using the AuthenticationManager to perform the sign in.

The problem I am having is that I'm not sure how to access the claims in the rest of my application, either in Controllers or in Razor Views.

I had tried the approach listed in this tutorial

For example, I tried this in my Controller code in an attempt to get access to the values passed into the Claims, however, the user.Claims is equal to null

var ctx = HttpContext.GetOwinContext();
ClaimsPrincipal user = ctx.Authentication.User;
IEnumerable<Claim> claims = user.Claims;

Perhaps I am missing something here.

Any help would be greatly appreciated and I apologise if this is a novice question, it's my first experience with OWIN and using Claims Identity.



Based on Darin's answer, I added his code but still I fail to see access to the Claims. Please see screenshot below showing what I see when hovered over identity.Claims.

Try this:

public ActionResult SomeAction()
    var identity = (ClaimsIdentity)User.Identity;
    IEnumerable<Claim> claims = identity.Claims;
