This document provides an overview of the ASP.NET MVC pipeline. It begins with an introduction to ASP.NET MVC and the basic MVC pattern of controller, model, and view. It then details each stage of the ASP.NET MVC request pipeline including controller factories, routing, action invokers, model binders, action filters, action results, and view engines. For each component, it provides a brief description and relevant interfaces. The document aims to explain the underlying process and components that handle requests in ASP.NET MVC.
