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 documen

Answer 1

I used below snippets in one sample asp.net web page page_load for starting to grasp the way ASP Identity works

   UserManager userManager = new UserManager();
    var roleStore = new RoleStore(new ApplicationDbContext());
    var roleManager = new RoleManager(roleStore);
    var applicationRoleAdministrator = new IdentityRole("superadmin");
    if (!roleManager.RoleExists(applicationRoleAdministrator.Name))
    {
        roleManager.Create(applicationRoleAdministrator);
    }
     ApplicationUser applicationUserAdministrator = userManager.FindByName(User.Identity.Name);

    if (!userManager.GetRoles(applicationUserAdministrator.Id).Contains("superadmin"))
    {
        Response.Redirect("~/account/login.aspx?ReturnUrl=" + Request.Url.AbsolutePath);
    }

Of course below ApplicationDbContext is automatically generated with ASP.NET 4.5+ templates like below

 public class ApplicationDbContext : IdentityDbContext
    {
        public ApplicationDbContext()
            : base("DefaultConnection")
        {
        }
    }

Also Create application Role Manager class too

public class ApplicationRoleManager : RoleManager
{
    public ApplicationRoleManager(IRoleStore roleStore)
        : base(roleStore)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions options, IOwinContext context)
    {
        //return new ApplicationRoleManager(new RoleStore(context.Get()));
        return new ApplicationRoleManager(new RoleStore(new ApplicationDbContext()));
    }
}

also add below line in your startup.Auth.cs => ConfigureAuth(IAppBuilder app) method

  app.CreatePerOwinContext(ApplicationRoleManager.Create);

And then in your controller:

private ApplicationRoleManager _roleManager;

public ApplicationRoleManager RoleManager
{
    get
    {
        return _roleManager ?? HttpContext.GetOwinContext().Get();
    }
    private set
    {
        _roleManager = value;
    }
}

I am new to this Identity Stuff and I am not sure if it is necessary or I am doing it clean and right, but these steps worked for me
