Microsoft ASP.NET MVC 4.0

A new Model-View-Controller (MVC) framework on top of the existing ASP.NET 3.5 runtime

ASP.NET MVC 4 is a framework for developing highly testable and maintainable Web applications that follow the Model-View-Controller (MVC) pattern.

The framework encourages you to maintain a clear separation of concerns— views for UI, controllers for handling user input, and models for domain logic.

ASP.NET MVC applications are particularly suited for unit testing and using test-driven development (TDD) techniques. ASP.NET MVC 4 makes it easy to write applications for the mobile web through adaptive rendering and device specific display modes.

ASP.NET MVC 4 also includes ASP.NET Web API, a framework for building and consuming HTTP services that can reach a broad range of clients including browsers, phones, and tablets. ASP.NET Web API is great for building services that follow the REST architectural style, plus it supports RPC patterns.

The name Microsoft ASP.NET MVC stands for Microsoft ASP.NET Model-View-Controller.

Additional Requirements: PowerShell 2.0, .NET 4, ASP.NET 4, and Visual Studio 2010 SP1 or Visual Web Developer 2010 SP1 are required to use this feature.
