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.

Below is an alternative implementation of a  create user  controller method using Claims based roles    The created claims then work with the Authorize attribute e g   Authorize Roles    Admin  User    User Create            POST api User Create      Route  Create        public async Task lt IHttpActionResult gt  Create  FromBody CreateUserModel model                if   ModelState IsValid                        return BadRequest ModelState                         Generate long password for the user         var password   System Web Security Membership GeneratePassword 25  5               Create the user         var user   new ApiUser     UserName   model UserName            var result   await UserManager CreateAsync user  password           if   result Succeeded                        return GetErrorResult result                         Add roles  permissions  for the user         foreach  var perm in model Permissions                        await UserManager AddClaimAsync user Id  new Claim ClaimTypes Role  perm                       return Ok lt object gt  new   UserName   user UserName  Password   password

I had the same challenge  This is the solution I found to add users to roles   internal class Security       ApplicationDbContext context   new ApplicationDbContext         internal void AddUserToRole string userName  string roleName                var UserManager   new UserManager lt ApplicationUser gt  new UserStore lt ApplicationUser gt  context             try                       var user   UserManager FindByName userName               UserManager AddToRole user Id  roleName               context SaveChanges                      catch                       throw

Are you looking for something like this   RoleManager   new RoleManager lt IdentityRole gt  new RoleStore lt IdentityRole gt  new MyDbContext      var str   RoleManager Create new IdentityRole roleName      Also check User Identity

While I agree with the other answers regarding the RoleManager  I would advice to examine the possibility to implement Authorization through Claims  Expressing Roles as Claims     Starting with the  NET Framework 4 5  Windows Identity Foundation  WIF  has been fully integrated into the  NET Framework   In claims-aware applications  the role is expressed by a role claim type that should be available in the token  When the IsInRole   method is called  there is a check made to see if the current user has that role   The role claim type is expressed using the following URI    http   schemas microsoft com ws 2008 06 identity claims role   So instead of using the RoleManager  you can  add a user to a role  from the UserManager  doing something like this   var um   new UserManager    um AddClaimAsync 1  new Claim  http   schemas microsoft com ws 2008 06 identity claims role    administrator       With the above lines you have added a role claim with the value  administrator  to the user with the id  1       Claims authorization  as suggested by MSFT  can simplify and increase the performance of authentication and authorization processes eliminating some back-end queries every time authorization takes place   Using Claims you may not need the RoleStore anymore   AspNetRoles  AspNetUserRoles

This one works for me  You can see this code on AccountController -  Register  var user   new JobUser   UserName   model Email  Email   model Email    var result   await UserManager CreateAsync user  model Password   if  result Succeeded          add this to add role to user      await UserManager AddToRoleAsync user Id   Name of your role        but the role name must exist in your AspNetRoles table
