Areas Implementation in Routing First Create Area(Admin) using VS and add the following code into Startup.cs First Way to Implement:- Add Controller Login and Index Action and add Following Code, [Area(“Admin”)] is compulsory to add on controller level to perform asp.net areas Routing. Startup.cs

 app.UseMvc(routes =>
            {
                routes.MapRoute(
                  name: "areas",
                  template: "{area:exists}/{controller=Login}/{action=Index}/{id?}"
                );
            });

Note: Area routing must be placed first with non area routing, area: exists is compulsory to add area routing.

Controller Code:

[Area("Admin")] 
    public class LoginController : Controller
    {
        public IActionResult Index()
        {
            return Content("Area Admin Login Controller and Index Action");
        }
    }

This route may be called using http://localhost:111/Admin

Second Way to Implement Area Routing:- Add Following code into startup.cs.

app.UseMvc(routes =>
            {
                routes.MapAreaRoute(
    name: "default",
    areaName: "Guest",
    template: "Guest/{controller}/{action}/{id?}",
    defaults: new { controller = "GuestLogin", action = "Index" });
            });

Create an Area “Guest”, Add “GuestLogin” Controller and “Index” Action and add the following code into the newly created controller.

[Area("Guest")]
    public class GuestLoginController : Controller
    {
        public IActionResult Index()
        {
            return Content("Area Guest Login Controller and Index Action");
        }
    }

This route may be called using http://localhost:111/Guest

With .net core, following is needed to be added in the startup file if you are adding an area:

     app.UseMvc(routes =>
            {
                routes.MapRoute(
                  name: "areas",
                  template: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
                );
            });

After that you can just simply mark your area and route in the controller, i.e
     [Area("Order")]
     [Route("order")]

it works for me.
