Summary

ASP.NET Web API is a powerful new way to add APIs to your new and existing web applications. MVC developers will find its controller-based programming model familiar, and WCF developers will find its support for both web-hosting and self-hosting to be an added bonus compared to MVC-based service systems. When coupled with Visual Studio 2012 and .NET 4.5, the asynchronous design allows your Web APIs to scale efficiently while maintaining a comfortable sequential programming model.
