This document provides an introduction to ASP.NET MVC for beginners. It discusses some of the weaknesses of traditional ASP.NET WebForms, such as lack of separation of concerns. ASP.NET MVC follows the Model-View-Controller pattern to address these issues by separating the user interface (view), data and business logic (model), and application logic (controller). The MVC pattern promotes loose coupling, testability, and maintainability. ASP.NET MVC builds on ASP.NET to provide a testable alternative to WebForms that supports clean URLs, separation of concerns, and extensibility. It demonstrates the MVC request processing flow from controller to model to view to response.
