An application is divided into three primary logical components using the Model-View-Controller (MVC) architectural pattern: the model, the view, and the controller. The MVC pattern is primarily used to control the software side of an application.
Each component's role is clearly defined in an MVC design application. Model classes, for instance, simply contain the data and the business logic. They do not handle HTTP requests. Views merely present data. The controllers take care of processing user input, responding to it, and choosing which model to transfer to which view. This is what is meant by division of duty. It makes an application simple to create and maintain as it evolves and becomes more complicated.
Web Pages, Web Forms, and MVC are the three main development formats that ASP.NET offers. The ASP.NET MVC framework integrates with the pre-existing ASP.NET capabilities, like master pages, authentication, etc. It is a compact, highly testable presentation framework. Additionally, the ASP.NET MVC framework is built on top of the ASP.NET framework, which means most of the features available in ASP.NET can also be used in MVC.
Thus, the best framework for many applications would be ASP.NET MVC.
