What is Web API?

Web API a new framework for creating HTTP services that can reach a broad range of clients including browsers and mobile devices.

Modern HTTP programming model- Directly access and manipulate HTTP requests and responses in your Web APIs using a clean, strongly typed HTTP object model.

Not linked MVC – you can use alone (Web Forms, WPF, etc..)

Ideal platform for Building RESTful Applications
