1. Describe the life cycle of an MVC application?
Any web applicationās two main execution steps are as follows:
ā Recognizing the desire
ā Delivering a suitable reaction.
There are two primary phases in an MVC application life cycle:
ā The request object is being created.
ā Response to the browser is sent.
2. What do you think MVC filters mean?
Action methods in MVC are mutually exclusive and determined by controllers and UI controls. Example: The UserController class has the UserAdd and UserDelete functions. However, we frequently wish to do something before or after a particular operation. Using the ASP.NET MVC feature, pre- and post-action behaviors can be added to the controllerās action methods.
3. What does the controllerās before render() function do?
When we manually call render() before the conclusion of a particular operation, this function is necessary. Before the view is rendered and after the logic for the controller action, this method is invoked. It is hardly frequently used.
4. Define DispatcherServerlet?
A class called DispatcherServerlet is responsible for receiving incoming requests and assigning them to the most appropriate resources, such as Views, Models, and Controllers.
5. What in MVC is attribute-based routing?
In ASP.NET MVC, a new attribute route has been added. The routing element can be used to determine URL structure. If the route property is used to decorate the GotoAbout action, indicates that GotoAbout can be called using the Users/about URL structure.
6. How does the MVC pattern handle routing?
Registered routes in the program comprise the route collection, or group, of routes. The collection routes are recorded through the RegisterRoutes method. If the request meets the pattern, the route and a handler define the URL pattern. The first parameter of the MapRoute is the name of the route; the second is the pattern that the URL matches; and the third is the default values for the Placeholders.
7. What distinguishes ViewResult from ActionResult?
ActionResult is an abstract class, and ViewResult is inherited from AbstractResult. When you are dynamically deriving various types of views, ActionResult is useful. FileStreamResult, ViewResult, and JsonResult are ActionResultās descendant classes. This is a common asp.net MVC interview question for experienced.
8. Describe NonActionAttributeās significance?
If we want to stop a public method of a controller from being used as an action method by default, we can do so by giving it the NonActionattribute.
9. Define the partial view in MVC?
The MVC partial view renders a portion of the view content. This lessens the need for code requests. The partial view enables the display of a view inside the parent view.
10. Describe MVC Scaffolding?
For ASP.NET web apps, MVC Scaffolding is a framework for code creation. When we want to quickly add code that communicates with data activities in our project, we use scaffolding. Field page templates, filter templates, and entity page templates are included. These scaffold templates make it possible to construct a working data-driven website quickly.
11. Explain ORM and its application?
A framework called the ORM (object-relational mapping) aids in minimizing the amount of handwritten code in a web application. When there arenāt any strict performance requirements, ORM is employed; nevertheless, high-load applications might use frameworks like Dapper.
12. Describe the POST and GET action types?
A resource provided by the POST action type receives data to process. With every POST request, we include the crucial URL and data. Overloads may be Absorbed.
A resource provided by the GET action type is asked for data. With each GET request, the required URLs are passed. Overloads may be absorbed.
13. How will MVC validation be implemented?
With the aid of validators established in the System, we can implement validation in the MVC application.ComponentModel. Namespace for DataAnnotations. The many validators include StringLength, Required, Range, and DataType.

15. Give us an example of when employing an IoC container was
Advantageous?
The advantages include external management of every objectās life, future contract implementation changes, dependency list changes that do not affect things utilizing the service, and sharing one instance by numerous unrelated Customers.
16. What is Spring MVC?
A Java framework called Spring MVC creates web applications by using the MVC design pattern. It carries out all of the fundamental components of the spring framework, including dependency injection and inversion of control. Spring MVC offers a classy method for using MVC in the Spring Framework with DispatcherServlet. This class translates incoming requests to view models and controllers after receiving them.
17. What does MVCās ViewState term mean to you?
ViewState is the basis for one of the most typical asp.net interview questions. In contrast to WebForms, MVC lacks ViewState. This is because ViewState is saved in a hidden field on the page, considerably increasing its size and slowing down page loading.
