Asp.net MVC 5 can't get user roles

Question

I'm trying to get user roles and modify it. I've tried many ways to get user roles but nothing works. Is there anything missing? I can get right User entity but Roles is always null. Is there any way to do it correctly? Thanks

var user = UserManager.Users.Single(u=>u.Id==id);
var roles = user.Roles;
roles.Add(....)


var user = UserManager.Users.Single(u=>u.Id==id);
user.IsinRole("rolename");

You can get them via claims:

var roles = ((ClaimsIdentity)User.Identity).Claims
            .Where(c => c.Type == ClaimTypes.Role)
            .Select(c => c.Value);

To add a user to a role, you can do ( Make sure the role exists in the database though ):

var roleresult = UserManager.AddToRole(currentUser.Id, "RoleName");
