ASP.NET MVC 5 Helllo World

Buiding a example simple with ASP.NET MVC5. we can see, many developer program ASP.NET MVC 5
Today, I will shared buiding way create project ASP.NET MVC 5, with program Visual Studio 2019
Everyone,can download here:https://docs.microsoft.com/en-gb/visualstudio/releases/2019/release-notes
Installing, note you tab open Individual Components, after then, you choose Class Designer and LINQ to SQL Tools

Setup project ASP.NET MVC 5
You create project

You choose ASP.NET Web Application, let's go, you can need choose Version Framework
After create success project, you can add news HomeControler.cs file in Controllers directory

Ok, Begin you create layout project

• Create Shared folder in directory Views
• Create _LayoutPage1.cshtml file in Views/Shared directory

you create layout razor success!, you open HomeController.cs, click-right function index()-> choose add view

You have new Index.cshtml file in Views/Home/Index.cshtml directory
Continue! you need to Controllers/HomeController.cs open it and configuration function index(), the folllowing below code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MVC5_HelloWorld.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            ViewBag.title = "MVC5 - Hello World";
            return View();
        }
    }
}

We set ViewBage.title to insert a string of data or an array of data that we want it to be displayed outside of View
You can using LinQ, you can see the following below

//HomeController.cs
var data = (from s in _db.users select s).ToList();
ViewBag = data;
return View()

//Views/Home/Index.cshtml
@foreach(var result in ViewBag.data){

  <span>@result.name</span>
  <span>@result.created_at</span>
}

The above is an example if you want to retrieve data in SQL SERVER, to display outside the View

Continue to you Views / Home / Index.cshtml and open up and edit the following:

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_LayoutPage1.cshtml";
}

<h2>@ViewBag.title</h2>

That's it, you can Run the project and test it out!
