Dot Net Interview Question: Create first Asp.Net MVC application

In this tutorial we will learn how to create a MVC project.

Asp.net MVC is basically an architectural pattern , which allow us to create a dynamic website using HTML. This gives feature of "TDD development".

Following some steps for creating your first Asp.net MVC projects.

1. Open visual studio and click on

2. File -> New -> Project

3. Here you will see a screen from here select Web and ASP.NET MVC4 Web Application and give the name for this project and click OK.

4. When we will click ok we will see Asp.Net New MVC project screen from here select “Empty template “ and select Razor as ViewEngine .

Razor And ASPX are type of ViewEngine.

Here we will prefer “VIEWeNGINE” because it is much clean and better in use.

5. After click on OK ,It will create a MVC project. In Solution explorer we will see “Modal”, “view” , “controller” folder .

6. Now go to controller folder and add a new controller to the project .

Right click on Controllers folder -> Select Add -> Controller

Give the name for this controller As FirstController and click on Add and it will generate a file with the name FirstController .

Here when you will click on add , this will add a class “FirstController.cs” class. it will be available in controller folder. This class will be inherited by “Controller” Base class

Here this class will contain a method and the return type of this method is “ActionResult”

7. Add ActionMethod To the Controller class

ActionMethods are used for handling “user request” , validation of user input, execute code and the o/p.

MVC routing engine send the user request to the appropriate ActionMethod.

Now open “FirstController.cs” Class and add a ActionMethod and the give name it as “Index”

The following code which is introduce in FirstController.cs Class

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

namespace FirstMvcApplication.Controllers

{

public class FirstController : Controller

{

// GET: /Home/

public string Index()

{

return "Hello, from first MVC application";

}

There is a function “index” which will return String , now at this point if you will run this application it will deploy at local server and will give the output.

8. Here in this condition if you will run this application it will give error.it is because if you will go to

App_Start -> RouteConfig.cs class there is code which contain first which method and which controller class to be execute.

Here by default controller name is “Home” but we don’t have controller name with this name. So for execution this change the name of controller from Home to First.

Change this Home Controller to First controller For this code is below

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using System.Web.Routing;

namespace FirstMvcApplication

{

public class RouteConfig

{

public static void RegisterRoutes(RouteCollection routes)

{

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(

name: "Default",

url: "{controller}/{action}/{id}",

defaults: new { controller = "First", action = "Index", id = UrlParameter.Optional }

);

}

9. Now Run your application it will output as "Hello, from first MVC application"

10. At this time this application is running on local sever for deploying this application IIS sever there are some steps

Go to start -> press Run - > in Run window type “InetManager”

Go to Control panel -> Administrative Tools - > search for Internet Information Services (IIS) Manager

Here if you are not able to see Internet Information Services (IIS) Manager then install it in your system. For this go to How To install IIS Server

11. On IIS server screen you are not able to see your application (FirstMVCApplication ) so for this go back to you application and right click on your application and go to properties click on WEB you will see there that you are using visual studio development server but instead of that we want to use local IIS web server so for this check redio button.

You remember that for creating you application on IIS server you have to open VS2010 as “Run as Administrator”.

Now click on Create virtual directory

12. After creating virtual directory again go to IIS server refresh it then you will see there your application. It means now your application will run on IIS server.
