Hello World MVC Application

In this post we shall create a Hello World Asp.Net MVC 2 Application from the scratch. We will make use of the Empty Web Application template to create this sample so that we will understand the basics of MVC. Follow the below steps to create the first MVC 2 Hello World Application

1. Open Visual Studio 2008
2. Create a new Project of type Asp.Net MVC 2 Empty Web Application
3. Give a Name, Location and save the Project
4. This will create a basic Project structure.
5. Right click on the View folder and select Add -> New Folder
6. Name the folder as “HelloMVC”
7. Now Right click the HelloMVC folder and select Add -> View
8. Name the file as “Index”
9. If the “Select Master Page” checkbox is checked, remove it and click Add
10. Now, Right click on the Controllers folder and select Add -> Controller
11. Name the controller as “HelloMVCController” and click Add
12. Open the controller file and add a Message key to the ViewData collection as follows.

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

namespace MvcSample.Controllers
    public class HelloMVCController : Controller
        // GET: /HelloMVC/
        public ActionResult Index()
            ViewData["Message"] = "Hello ASP.NET MVC";
            return View();
11. Now open the Index.aspx View file, and modify the code to read the Message key as follows.

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
         <h2><%= Html.Encode(ViewData["Message"]) %></h2>

12. Now, Build and run the application
13. In the address bar append /HelloMVC/ to the root path.
14. The page opens up and displays “Hello ASP.NET MVC”
15. That’s it we have created a Hello World MVC Application.
