We're all very excited about shipping VS 2005 and .NET Framework 2.0! Woohoo!
Our earlier LINQ Tech Preview release worked as an add-on to VS 2005 Beta 2, and we are happy to have an updated LINQ release that works with the final VS 2005 bits. See the LINQ page or Visual C# Futures page to get the new download. While VS 2005 is final and release-quality, please bear in mind that our LINQ Tech Preview is definitely not. We are making these pre-release bits available so that we can get early feedback. Thanks!
