Route user to correct area

Question

When a user logs in. I'm looking for a way to route a user to the correct area based on their role in identity.

I've tried:

• You have the default controller that you can redirect to that area return RedirectToAction("Index", "Dashboard", new { area = "Admin" });, but I have multiple roles.
• Add a rewrite option in the StartUp Configure method. Which works in the beginning, but if you have a link to another area - it doesn't work.
• On the default controller I created a view. Added some razor @if (User.Identity.IsAuthenticated && User.IsInRole("Admin")) else if(). Then used <text>and <script> tags in between the if statements to call a function that would redirect the user. It didn't provide an error, just didn't work. I figured it wouldn't, but... trying to think outside the box

Thanks ahead for the ideas!

If you are using asp.net core identity,in controller, you could directly use var isInRole = User.IsInRole("Admin") to check whether current user has an Admin role.

Or use UserManager to get current user and all his roles:

private readonly UserManager<IdentityUser> _userManager;
public HomeController(UserManager<IdentityUser> userManager)
{
    _userManager = userManager;
}

[Authorize(Roles = "Admin")]
public async Task<IActionResult> TestView()
{
    var user = await _userManager.GetUserAsync(HttpContext.User);

    var roles = await _userManager.GetRolesAsync(user);

    var matchingvalues = roles.SingleOrDefault(stringToCheck => stringToCheck.Equals("Admin"));
    if(matchingvalues != null)
    {
        return RedirectToAction("Index", "Dashboard", new { area = "Admin" });
    }

    return View();
}
