Difference between WCF Web API and WCF Data Services

Question

What is the difference between WCF Data Services and WCF Web API?

Answer 1

WCF Data Services is a framework on top of WCF that makes it easy to create RESTful services that "talk" Atom/OData based on specified LINQ context (object model, LINQ2SQL or Entity Framework).

The new WCF Web APIs are currently under development, and will enhance the existing WCF framework to build better HTTP/RESTful services in general.
