If you’d like to query AspNetUserRoles table directly, you can try following approach.

Inject an instance of ApplicationDbContext

private readonly ApplicationDbContext _appdbcontext;

public HomeController(ILogger<HomeController> logger, ApplicationDbContext appdbcontext
    //...
    )
{
    _logger = logger;
    _appdbcontext = appdbcontext;
    //...
}

Query AspNetUserRoles table

var roleIds = _appdbcontext.UserRoles.Where(u => u.UserId == user.Id).Select(r => r.RoleId).ToList();

Method 2

You can do,

var roleIds = _userManager.FindById(User.Identity.GetUserId()).Roles.Select(r => r.RoleId);
