Let’s understand the differences between each of the versions in breif.

MVC 2 : It has asynchronous controllers and templated helpers which performs client side validation.

MVC 3 : Razor language is introduced and HTML5 enabled templates.

MVC 4 : It supports ASP.Net Web API.

MVC 5 : It supports attribute based routing and authentication filters.

MVC 6 : It supports deployment of runtime and framework with application so no need to compile every time. Dependency injection is enabled and you can esaily manage using Nuget packages.

Filters are performs before and after action behaviors on controller’s action methods.

It is a reusable view which can embedded into another view. You can reuse leftmenu,header and footer controls for every pages.

Areas are used to divide or “isolate” the modules of large applications in multiple or separated MVC.

It is a code generation framework.You can easily add scaffolding to your project to quickly interacts with data models.

• ActionResult is an abstract class that contain the below subclass.
• ViewResult – Renders a specifed view to the kickback stream
• PartialViewResult – Renders a specifed partial view to the kickback stream

It is used to add a specific contraint to the URL and defined in RouteConfig.cs file.

TempData is the current request sent by the user. To read this, we need to Keep method,

It is defined below,

@TempData[“Data”];

TempData.Keep(“Data”);

And,

Peek function helps to read and maintain “TempData” for the subsequent request.It is defined below,

string peek = TempData.Peek(“Data “).ToString();

It is used to squeeze and remove whitespace and performs compression technique to make the downloaded files as small as possible.

It is the process of validate specific data posting data to a server without posting the entire form data to the server

Unobtrusive JavaScript is a general access to the purpose of JavaScript in web pages. It is based on below concepts,
It separates the functionality from a Web page structure/content
Progressive enhancement to support user agents which is not supported in advanced JavaScript functionality

It is used in AJAX appllication. The JSON result object that serializes the spiced object to JSON format. It is defined below,

public JsonResult JsonResultTest()

{

return Json(“Hello World!”);

}

It is used to build HTTP services for clients, including browsers and mobile devices.

ASP.NET Web API acts as a principle platform for building RESTful applications on the .NET Framework.

Web security class provides Login,ResetPassword and CreateAccount features for developing web applications.

MVC uses JsonValueProviderFactory to allow action methods to accept data from model and bind the data in Json format.

It is defined in the System.Web.Mvc.ActionResult namespace. It is used to redirect the application actions to specific resource.

NonAction method is an attribute. By default all the methods in MVC framework as public. If you want to change the method as private, you can assign as NonAction method.

It is used to combine multiple files into single file.

It is used to reduce hosting and the database connection defined in the server roud trips.

The following ways Web Forms differs from MVC,
Web Forms are tightly connected with logic but MVC separates logic part.
Web Forms are file based routing but MVC is URL based routing.
Web Forms uses master page concept but MVC supports layout approach.
Web Forms supports its own syntax but MVC supports Razor syntax.

MVC uses HandleError method to handle exception filters. We use this approach in action method in Controller class to handle errors.

It is used to apply views to all pages automatically.

It is an attribute. It is used to apply validation to both client and server side.

It is used to set the maximum and minimum string length for the property. It is defined below,

We can send message that validate input from server side and return validation message from server side.

It is used to render an anchor tag to redirect another page.

It is a kind of malicious attack from user tries to access entries via input fields.

It is the process of customize your applications for the current features.

It is a resource file generator which is used to convert .resx file to .resources file.

It provides information about an asynchronous action method for name,Controller and its parameters.

It is the part of HTML which is used to render in layout page. It is defined below,

@RenderSection(“Demo”)

Here,

Demo is the child page which can be implemented as,

@section Demo{

<p>Hello…</p>

}

Code Blocks are starts with @ char and enclosed by {} braces. The default language in code block as C# which is used to change to HTML.

It is used to store user specific information. This information can be read from the user whenever visits the web site.

It is used to find and install all the packages to add the application.

It is used to represent the user defined contents in the action method.

We can maintain Session in the following ways,

TempData
ViewData
ViewBag

It is not defined in Layout page and designed specifically to render view.

It is like a Void method and Whenever you don’t want to return to Client side, you can use this method.

JsonMediaTypeFormatter
XmlMediaTypeFormatter
FormUrlEncodedMediaTypeFormatter
JQueryMvcFormUrlEncodedFormatter

It is used to create web applications and provide dynamic link between the client and server.

It is start of breaking the program into various distinct features which overlaps in functionality as little as possible. MVC pattern involvement on separating the content from presentation and data-processing from the content.

TempData is a key, value pair as ViewData. This is descript from the “TempDataDictionary” class. TempData is used when the data is to be used in two consecutive requests, this could be between the actions or the controllers. This requires typecasting in view.

ViewStart page is used to make sure the common layout page will be used for multiple views. The code written in this file will be accomplished first when the application is being loaded.

Visual Studio Express edition can be added only in Professional and Ultimate versions of Visual Studio.

There are two methods for adding constraints to the route is Using regular expressions and object that implements IRoute Constraint interface.
