The news are out. The ADO.NET Data Services Framework (Astoria) and the ADO.NET Entity Framework will be shipping as part of .NET 3.5 SP1, and the Beta 1 release is now available. All the official blogs discussed the details already, including the Astoria team blog, ADO.NET team blog, Scott's, and many others out there.
Folks out there trying Astoria and the EFx have been working on bits from last December for a while. Finally we have a newer release for everyone to take a look, try stuff and send feedback.
In addition to the release of the framework and VS, we also put out the Data Services AJAX library in codeplex.
This is the last beta before we're done, so give this release a shot and let us know what you find!
