Scott give us a nice preview of Astoria (ADO.NET Data Services) and show up some of the internal working, (how the magic happen as he put i). I really like that part of the presentation since I really like to know what’s going when code is generated by the IDE.
Data Services allow you to present some entities as REST services, it return both XML (Atom) and Json. Data Services comes in the new VS 08 and .NET 3.5 SP1.
I will going to check it out as soon as possible.
