ADO.NET Data Services (formerly known as Project “Astoria”)

The ADO.NET Data Services framework consists of a combination of patterns and libraries that enable the creation and consumption of data services for the web. The goal of the ADO.Net Data Services framework is to facilitate the creation of flexible data services that are naturally integrated with the web, using URIs to point to pieces of data and simple, well-known formats to represent that data, such as JSON and plain XML. This results in the data service being surfaced to the web as a REST-style resource collection that is addressable with URIs and that agents can interact with using the usual HTTP verbs such as GET, POST or DELETE.

Many of the Microsoft cloud data services (Windows Azure tables, SQL Data Services, etc.) expose data using the same REST interaction conventions followed by ADO.NET Data Services. This enables using the ADO.NET Data Services client libraries and developer tools when working not only with on premises services created using the ADO.NET Data Services Framework, but also with hosted cloud services.
