Project Codename "Astoria" – Announced at Mix 07

Today at Mix 07, the ADO.NET team will speak for first time about an incubation project that they have been working on, Project Codename “Astoria”.

With the announcement of Microsoft Silverlight and technologies like AJAX, a new wave of web applications are now being built that enable developers to build better, richer user experiences on the web. With these technologies we are seeing a much stronger separation of presentation from data in the organization of our web applications.

The goal of Microsoft Codename “Astoria” is to enable applications to expose data as a data service that can be consumed by web clients within a corporate network and across the internet. The data service is reachable over HTTP, and URIs are used to identify the various pieces of information available through the service. Interactions with the data service happens in terms of HTTP verbs such as GET, POST, PUT and DELETE, and the data exchanged in those interactions is represented in simple formats such as XML and JSON.

The first early release of Astoria will be a Community Tech Preview that you can download, as well as an experimental online service you can access over the internet.

Check out the Astoria webpage at for more information and a link to the download.
