Add role in ASP.NET Identity

Question

How can I add a Role in the new ASP.NET Identity system (1.0)? There is a UserStore class but no RoleStore class.

I can't find any documentation on this issue.

Answer 1

RoleManager = new RoleManager<IdentityRole>(
                  new RoleStore<IdentityRole>(new MyDbContext()));
var roleresult = RoleManager.Create(new IdentityRole(roleName));

Answer 2

Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework.

I would advice to examine the possibility, in my opinion the preferred, to implement Authorization through Claims (Expressing Roles as Claims).

When the IsInRole() method is called, there is a check made to see if the current user has that role. In claims-aware applications, the role is expressed by a role claim type that should be available in the token.

The role claim type is expressed using the following URI: "http://schemas.microsoft.com/ws/2008/06/identity/claims/role"

So from the UserManager you can do something like this (without the RoleManager):

var um = new UserManager();
um.AddClaimAsync(1, new Claim(ClaimTypes.Role, "administrator"));

Claims can simplify and increase the performance of authentication and authorization processes. You can use the roles stored as claims to eliminate back-end queries every time authorization takes place.

Using Claims you will not need the RoleStore anymore (at least for the equivalent authorization purposes...)
