Explain what a is Model-View-Controller.<\/strong><\/p>\n

MVC is a software architecture pattern for developing web applications. It is handled by three objects Model-View-Controller.<\/p>\n

Mention what does Model-View-Controller represents in an MVC application.<\/strong><\/p>\n

In an MVC model,<\/p>\n

Model\u2013 It represents the application data domain. In other words, application business logic is contained within the model and is responsible for maintaining data<\/p>\n

View\u2013 It represents the user interface, with which the end users communicate. In short, all the user interface logic is contained within the VIEW<\/p>\n

Controller\u2013 It is the controller that answers to user actions. Based on the user actions, the respective controller responds within the model and chooses a view to render that display the user interface.\u00a0 The user input logic is contained within the controller<\/p>\n

Explain in which assembly the MVC framework is defined.<\/strong><\/p>\n

The MVC framework is defined in the System.Web.Mvc.<\/p>\n

List out a few different return types of a controller action method.<\/p>\n

View Result<\/p>\n

Javascript Result<\/p>\n

Redirect Result<\/p>\n

JSON Result<\/p>\n

Content Result<\/p>\n

Mention what is the difference between adding routes, to a webform application and an MVC application.<\/strong><\/p>\n

To add routes to a webform application, we can use the MapPageRoute() method of the RouteCollection class, where adding routes to an MVC application, you can use the MapRoute() method.<\/p>\n

Mention what are the two ways to add constraints to a route.<\/p>\n

The two methods to add constraints to a route is<\/p>\n

Use regular expressions<\/p>\n

Use an object that implements the IRouteConstraint Interface<\/p>\n

Mention what are the advantages of MVC.<\/strong><\/p>\n

MVC segregates your project into a different segment, and it becomes easy for developers to work on<\/p>\n

It is easy to edit or change some parts of your project making the project less development and maintenance cost<\/p>\n

MVC makes your project more systematic<\/p>\n

Mention what the \u201cbeforFilter()\u201d, \u201cbeforeRender\u201d and \u201cafterFilter\u201d functions do in Controller.<\/p>\n

beforeFilter(): This function is run before every action in the controller. It\u2019s the right place to check for an active session or inspect user permissions.<\/p>\n

beforeRender(): This function is called after controller action logic, but before the view is rendered. This function is not often used but may be required If you are calling render() manually before the end of a given action<\/p>\n

afterFilter(): This function is called after every controller action, and after rendering is done. It is the last controller method to run<\/p>\n

Explain the role of components Presentation, Abstraction, and Control in MVC.<\/strong><\/p>\n

Presentation: It is the visual representation of a specific abstraction within the application<\/p>\n

Abstraction: It is the business domain functionality within the application<\/p>\n

Control: It is a component that keeps consistency between the abstraction within the system and their presentation to the user in addition to communicating with other controls within the system<\/p>\n

Explain the role of \u201cActionFilters\u201d in MVC.<\/strong><\/p>\n

In MVC \u201c ActionFilters\u201d help you to execute logic while the MVC action is executed or is executing.<\/p>\n

\u00a0Explain what are the steps for the execution of an MVC project.<\/strong><\/p>\n

The steps for the execution of an MVC project include<\/p>\n

Receive the first request for the application<\/p>\n

Performs routing<\/p>\n

Creates MVC request handler<\/p>\n

Create Controller<\/p>\n

Execute Controller<\/p>\n

Invoke action<\/p>\n

Execute Result<\/p>\n<\/p>\n
