                </tr>
            }
        </tbody>

 Application Role:

public class ApplicationRole : IdentityRole<Guid>
{
    public string Description { get; set; }
}

viewmodel:

public class AdminDetailsViewModel
{
    public List<ApplicationUser> application { get; set; }
    public List<ApplicationRole> applicationRoles { get; set; }
}

Controller:

public async Task<IActionResult> Index()
{

    var app = from m in _context.Users
              select m;

    var approle = from m in  _context.UserRoles
                  select m;

    var Admininfo = new AdminDetailsViewModel
    {

        application = await app.ToListAsync(),
        applicationRoles = await approle.ToListAsync()  // I get a error here
    };

    return View(Admininfo);
}

Im not really sure how i should handle this
