The Model-View-Controller (MVC) pattern is undeniably the most popular and sought-after architectural pattern used in web application development, particularly in ASP.NET. Its structured approach to designing applications by separating data, presentation, and user interaction has made it a game-changer. The Model of MVC architecture in ASP NET represents data and business logic, the View handles production and user interface, and the Controller manages the data flow between the Model and View, creating a seamless flow that promotes modularity, maintainability, and testability.
