Asp.net and c#

When developing ASP.NET applications the need of reducing code duplication increases along with their complexity. This is because testing and performing changes become very difficult tasks when having many different sources of code with the same functionality. Model View Controller architecture (or pattern) allows us to separate different parts of our applications into tiers to fulfill this need. MVC Overview Model View Controller architecture aims to separate an application into three parts: Model:  It is the business logic of an application. From an object oriented perspective it would consist of a set of classes that implement the critical functionality of an application from a business point of view. View:  It can consist of every type of interface given to the user. In ASP.NET the view is the set of web pages presented by a web application. Controller:  This part of the architecture is the most difficult to explain, hence the most difficult to implement in many platforms
