i have created a role for a user in identity, but when i use it says not authorized

Question

i am using default identity provided by asp.netcore, i have made a role named admin and have also inserted related data in ASPNetUserRoles table, and on my controller i wrote [Authorize(Roles = "Admin")], but still when i try to access that controller, it says, not authorized. here are the following codes.

i have double checked that userid and roleid is correct

select id from AspNetUsers id 58005002-d0d4-4db1-b0bb-5a474cca8013

select * from AspNetRoles id name normalizedName ConcurrencyStamp c4a56464-53f7-440c-b904-fbc7389ed00a Admin ADMIN 080dbb2c-789e-4e28-95fd-6bc73d8b199e

select * from AspNetUserRoles UserId RoleId 58005002-d0d4-4db1-b0bb-5a474cca8013 c4a56464-53f7-440c-b904-fbc7389ed00a

[Authorize(Roles = "Admin")] public class AdminController : Controller {

    // GET: /<controller>/
    public IActionResult Index()
    {
        return View();
    }
}

i can access other controllers which are only authorized with no roles, but i am having problem with this.

Answer 1

Try to add roles to your services in Startup.cs file

public void ConfigureServices(IServiceCollection services)
{
    services.AddDefaultIdentity<IdentityUser>()
        .AddRoles<IdentityRole>();
}

Answer 2

From this post,try to register RoleManager<IdentityRole> like

services.AddDefaultIdentity<IdentityUser>()
   .AddRoles<IdentityRole>()
   .AddRoleManager<RoleManager<IdentityRole>>()
   .AddDefaultUI(UIFramework.Bootstrap4)
   .AddEntityFrameworkStores<DeadAliveDbContext>();
