Introduction:

ASP.NET Web API is a framework for building HTTP Services. This HTTP Services can be consumed by many clients like Desktop, Mobile. ASP.NET Web API was introduced with MVC4. ASP.NET Web API is very similar to ASP.NET MVC because it contains many features of ASP.NET MVC application like Controllers, ActionResult, filter, Routing, Dependency Injection. But you cannot link an ASP.NET WEB API to ASP.NET MVC application. You can think an ASP.NET Web ASPI to separate application. It works with HTTP Verbs so it has the support of conviction based CRUD operation. An ASP.NET Web API application can be hosted with an ASP.NET MVC application.
