ASP.NET MVC provides a framework that enables you to easily implement the model-view-controller (MVC) pattern for Web applications. This pattern lets you separate applications into loosely coupled, pluggable components for application design, processing logic, and display.
ASP.NET MVC is not a replacement for Webforms. It provides an alternative choice when designing a Web application. Using ASP.NET MVC offers the following advantages:
* It enables you to achieve and maintain a clear separation of concerns
* It facilitates test driven development (TDD)
* It provides more control over the URLs you publish in the application and over the HTML that is emitted by the application
Model-view-controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the Model represents the information (the data) of the application and the business rules used to manipulate the data, the View corresponds to elements of the user interface such as text, checkbox items, and so forth, and the Controller manages details involving the communication to the model of user actions such as keystrokes and mouse movements.
