How to add claims during user registration

Question

I'm using ASP.NET MVC 5 project with identity 2.1.0 and VS2013 U4. I want to add claims to user during registration in order to be stored in db. These claims represent user custom properties.
As I created a web page for administrator to create/edit/delete users, I'm still using create method from AccountController to create a user, but I don't want to login that user. How can I add those claims to the user ?

You probably already have a UserManager class. You can use that one to create users and to add claims.

As an example in a controller:

// gather some context stuff
var context = this.Request.GetContext();

// gather the user manager
var usermanager = context.Get<ApplicationUserManager>();

// add a country claim (given you have the userId)
usermanager.AddClaim("userid", new Claim(ClaimTypes.Country, "Germany"));

In order for this to work you need to implement your own UserManager and link it with the OWIN context (in the example it's ApplicationUserManager which basically is class ApplicationUserManager : UserManager<ApplicationUser> { } with only a small amount of configuration added).
