                endpoints.MapControllerRoute(
                    name: "default",

using System;

namespace LearnASPNETCoreMVC5.Controllers
{
    [Route("demo")]
    public class DemoController : Controller
    {
        [Route("index")]
        [Route("")]
        [Route("~/")]
        public IActionResult Index()
        {
            ViewBag.age = 20;
            ViewBag.fullName = "Kevin";
            ViewBag.status = true;
            ViewBag.price = 4.5;
            ViewBag.birthday = DateTime.Now;
            return View();
        }
    }
}

Create new folder named Views. In this folder, create new folder named Demo. Create new view named Index.cshtml as below:

<html>
<head>
    <meta name="viewport" content="width=device-width" />
