Introduction to MVC framework
ASP.NET MVC is a framework for building web applications that applies the general ModelView Controller pattern to the ASP.NET framework.
Components of ASP.NET MVC ModelsThese are the classes that represent the domain you are
interested in.
With ASP.NET MVC, this is most likely a Data Access Layer of some kind using a tool like Entity Framework or NHibernate combined with custom code containing domain-specific logic
ViewThis is a template to dynamically generate HTML
ControllerThis is a special class that manages the relationship between
the View and Model.

MVC APPLICATION STRUCTURE
Controllers Controllers within the MVC pattern are
responsible for responding to user input, often making changes to the model in response to user input. In this way, controllers in the MVC pattern are concerned with the flow of the application, working with data coming in, and providing data going out to the relevant view.
A Simple Example: The Home Controller
Home Controller Classusing System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcMusicStore.Controllers{Public class HomeController : Controller{public ActionResult Index(){ViewBag.Message = “I like cake!”;return View();}public ActionResult About(){return View();}}}
Creating the New Controller
Action Methods public class StoreController : Controller { // // GET: /Store/ public string Index() { return “Hello from Store.Index()”; } // // GET: /Store/Browse public string Browse() { return “Hello from Store.Browse()”; } // // GET: /Store/Details public string Details() { return “Hello from Store.Details()”; } } }
Parameters in Controller Actions // // GET: /Store/Browse?genre=?Disco public string Browse(string genre) { string message = HttpUtility.HtmlEncode(“Store.Browse,
Genre = “ + genre); return message; }
Parameters in Controller Actions
Razor View Engine Razor is the first major update to rendering
HTML since ASP.NET 1.0 shipped almost a decade ago. The default view engine used in MVC 1 and 2 was commonly called the Web Forms View Engine, because it uses the same ASPX/ASCX/MASTER files and syntax used in Web Forms
What is Razor? Razor is the response to one of the most
requested suggestions received by the ASP.NET MVC feature team — to provide a clean, lightweight simple view engine that didn’t contain the “syntactic cruft” contained in the existing Web Forms View Engine.
Many developers felt that all that syntactic noise
required to write a view created friction when trying to read that view.
View Example @{ Layout = null; } <!DOCTYPE html> <html> <head><title>Sample View</title></head> <body> <h1>@ViewBag.Message</h1> <p> This is a sample view. It’s not much to look at, but it gets the job done. </p> </body> </html>
