Asp Identity 2.0 adding new roles and adding user to roles

asp.netasp.net-identityvisual-studio-2013

I'm having trouble understanding the new Identity stuff. I'm trying to figure out how to add new roles and add user's to those roles. I'm trying to create a role management page and a user management page for my application and need to be able to do those two things. Everytime i try to add a role to a user like this: System.Web.Security.Roles.AddUserToRole("Andy", "admin"); I get "The Role Manager feature has not been enabled." I don't have a custom role provider and i tried turning role manager to enabled but just got an error about not having a role provider. I figured Identity had all this built in already? Can somebody help me through this?

System.Web.Security is the old ASP.NET Membership framework. ASP.NET Identity is in the namespace Microsoft.AspNet.Identity. Use a RoleManager to create roles, and a UserManager to add users to roles.

using (var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context)) 
{
    roleManager.Create(new IdentityRole("Administrator"));
}

using (var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context)))
{
    var user = new ApplicationUser { UserName = "admin" };
    userManager.Create(user, "admin321");
    userManager.AddToRole(user.Id, "Administrator");
}

Add User to Role ASP.NET Identity

I found good answer here Adding Role dynamically in new VS 2013 Identity UserManager

But in case to provide an example so you can check it I am gonna share some default code.

First make sure you have Roles inserted.

enter image description here

And second test it on user register method.

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser() { UserName = model.UserName  };

        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            var currentUser = UserManager.FindByName(user.UserName); 

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

            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("Index", "Home");
        }
        else
        {
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

And finally you have to get "Superusers" from the Roles Dropdown List somehow.

C# – ASP.NET Identity check user roles is not working

In that case you need to logout and login the user again.

Because the roles data is also stored in cookies, So you must issue the cookie again to work it.
