Update User Claim not Taking Effect. Why?

Question

I am using ASP.NET MVC 5.1 with Owin and Claims authentication.

After the user changes its email I need to update the users claims, so I tried in the controller:

Answer 1

This works for me. Not sure if it is the best way but the updated claim is in the DB and in subsequent controllers.

var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
var c = identity.Claims.FirstOrDefault(r => r.Type == "tId");
await UserManager.RemoveClaimAsync(user.Id, c);
await UserManager.AddClaimAsync(user.Id, new Claim("tId", "9032C945-DC5C-4FC9-BE7C-8EDC83A72E58"));

AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
AuthenticationManager.SignIn(new AuthenticationProperties { IsPersistent = isPersistent }, identity);
