Different technologies use the Model-View-Controller (MVC) architecture. Here, "M," "V," and "C" stand for, respectively, "MODEL," "VIEW," and "CONTROLLER."
MVC is not a language or a technology; it is architecture. Most businesses use the MVC design pattern when creating various applications. This design does not require a separate technology or language to operate.
The topic of ASP.NET MVC will be covered in this lesson. Microsoft created the web application framework known as ASP.NET MVC. The model-view-controller (MVC) design paradigm is used in this framework. It aids in the development of web applications that are well-structured. In 2007, Microsoft launched ASP.NET MVC.
Microsoft.NET Framework 3.5 is the very minimal requirement for constructing an ASP.NET MVC application. The System.Web.Mvc assembly in ASP.NET contains the MVC framework definitions.
Models: A model puts the application's data's logic into practise. Model is essentially a class written in C# or VB.NET that retrieves and stores model state in a database. Let's say your SQL Server database contains an Employee table. The Employee object may use information it has retrieved from a database, update that information, and then write it back to the Employee table.
Views: A view is a representation of your application's user interface (UI). Your user interface is often mapped using model data. If your model data consists of employee objects, you can design a user interface (UI) that shows text fields, drop-down menus, grid views, and check boxes dependent on the status of the employee objects.
Controllers: The MVC architecture's central component is the controller. The parts that coordinate the connection between the view and the model are known as controllers. Input is processed by the controller, who also works with the model and renders the view. The controller in an MVC application manages and reacts to user input and interaction whereas the view only shows information.
Numerous advantages, both actual and perceived, that ASP.NET MVC offers include:
The Model-View-Controller (MVC) architectural pattern divides an application into three main logical components: the model, the view, and the controller. Each of these components is made to deal with specific aspects of application development. MVC is one of the most extensively used and well-liked web development frameworks for creating scalable and adaptable projects.

In MVC, action methods are defined by controllers, and UI controls and these action methods are mutually exclusive. Example: The UserAdd and UserDelete functions are found in the UserController class. But frequently, we want to take some action either before or after a specific operation. Pre- and post-action behaviours can be introduced to the controller's action methods using the ASP.NET MVC capability.
We must complete 4 separate steps in order to generate a request object. Which are:
When adding routes to a webform application, we use the MapPageRoute() method from the RouteCollection class. While adding routes to an MVC application requires the MapRoute() function.
While an MVC action is being executed, logic is carried out via ActionFilters. Action filters also enable the use of action methods and pre- and post-processing logic.
