User.IsInRole returns nothing in ASP.NET Core (Repository Pattern implemented)

I have an ASP.NET Core (Full .NET Framework) application with the following configuration:


public void ConfigureServices(IServiceCollection services)
// Add framework services.
services.AddDbContext<ApplicationDbContext>(options =>

services.AddIdentity<ApplicationUser, IdentityRole>(p => {
p.Password.RequireDigit = true;
p.Password.RequireNonAlphanumeric = false;
p.Password.RequireUppercase = true;
p.Password.RequiredLength = 5;


// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
services.AddTransient<IDbFactory, DbFactory>();
services.AddTransient<IUnitOfWork, UnitOfWork>();

services.AddTransient<IUserRepository, UserRepository>();
services.AddTransient<IUserService, UserService>();

The ApplicationUser extends from IdentityUser and ApplicationDbContext extends IdentityDbContext

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
public ApplicationDbContext()
: base()

public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)

public virtual void Commit()

protected override void OnConfiguring(DbContextOptionsBuilder builder)

builder.UseSqlServer("connection string here");

protected override void OnModelCreating(ModelBuilder builder)

// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);

// Configure model
// Identity
new Configuration.Identity.ApplicationUserConfiguration(builder.Entity<ApplicationUser>());
new Configuration.Identity.ApplicationUserProfileConfiguration(builder.Entity<ApplicationUserProfile>());
new Configuration.Identity.RoleConfiguration(builder.Entity<IdentityRole>());
new Configuration.Identity.RoleClaimConfiguration(builder.Entity<IdentityRoleClaim<string>>());
new Configuration.Identity.ApplicationUserRoleConfiguration(builder.Entity<IdentityUserRole<string>>());
new Configuration.Identity.ApplicationUserClaimConfiguration(builder.Entity<IdentityUserClaim<string>>());
new Configuration.Identity.ApplicationUserLoginConfiguration(builder.Entity<IdentityUserLogin<string>>());
new Configuration.Identity.ApplicationUserTokenConfiguration(builder.Entity<IdentityUserToken<string>>());

Here is my demo data:

Role table

Role table

User table

User table

UserRole table

UserRole table

In my Login Action i have the following:

public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
// This doesn't count login failures towards account lockout
// To enable password failures to trigger account lockout, set lockoutOnFailure: true
var result = await _signInManager.PasswordSignInAsync(model.Username, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
if (User.IsInRole("Admin"))
return RedirectToAction("Index", "Home", new { area = "Admin" });
return RedirectToAction("Index", "Home");
if (result.RequiresTwoFactor)
return RedirectToAction(nameof(SendCode), new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
if (result.IsLockedOut)
_logger.LogWarning(2, "User account locked out.");
return View("Lockout");
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);

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

What i want to achieve is to redirect the user to a certain area after login.

The current problem i'm facing is that the function
returns false and in debug mode, if i look at the usermanager, the current user doesn't have the roles loaded (Count = 0).

Any thoughts would be appreciated.

Update 1

Ignore the Role Id cause is wrong. In fact the user is mapped with the correct value.

User.IsInRole is checking the cookie. But you are checking this within the same http request as you sign-in. Cookie is simply not there yet - it will be available on the reply or next request.

At that point you need to use ApplicationUserManager.IsInRoleAsync(TKey userId, string role) to check against the database.
