It was a time I was hearing and reading about the LINQ project. Some said that its an O/R Mapping platform from microsoft, some said it's language enhancements on C# and so on. I've just downlaoded and installed the LINQ project May 2006 CTP from microsoft.com (don't have the link right now, you'll need to search for it :P).
Actually LINQ was everything I've heard. It has three major concepts which all are Language Integrated Query mechanisms. You'll face with some new enhancements to VB and C# languages which help you query data structrues such as array lists (IEnumerables) and dataset. It will bring XLinq which is the LINQ service on XML in all kinds and DLinq which is much like an O/R Mapper or Persistence layer with many codeing inline facilities.
Anyway, life is getting much more easier. Hola microsoft's fellas.
