Amanda Silver at the Visual Basic Team Blog:
I’m very excited to announce that the next tech preview of Visual Basic 9.0 which includes support for Language INtegrated Query (codename LINQ) and XML integration atop the XLinq API is now available on the VB Future and the LINQ project websites. This is the result of a ton of hard work for a significant portion of the team and we’re very happy to get it out to you.
This is an additive release to that which came out in the PDC timeframe. It expands the XML integration in both the language and IDE, provides some editor features for the LINQ syntax, and enables DLinq for VB.
