{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Demo}/{action=Index}/{id?}");

    public class DemoController : Controller
    {

        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:
