This document provides an overview of ASP.net MVC, including: - ASP.net MVC is based on the Model-View-Controller pattern which separates application logic, UI, and data access for better organization and testability. - MVC frameworks like Rails, Django, and ASP.net MVC itself use MVC to provide routing, controllers that interact with models and pass data to views, and views that are responsible for output. - ASP.net MVC controllers direct requests, interact with models to retrieve data, and send data to appropriate views, separating concerns compared to traditional ASP.net.
