The VB team just posted some Hands On Labs on LINQ and LINQ to SQL for Orcas Beta 1. The first lab provides an introduction to The LINQ Project. You’ll look at basic LINQ features including the Standard Query Operators, and you’ll see how these features can be used against in-memory collections, connected databases, and XML documents. The second lab aims to provide a clear picture of the relational data access support provided by the LINQ Project, referred to as LINQ to SQL.
