Yesterday I arrived in Barcelona for TechEd 2007. I followed already some interesting sessions about LINQ, it brings you closer how you can access data in a more intuitive and more object-oriented way (data = objects). I really like LINQ to SQL, one of the drawbacks, is that it can only be used against a SQL Server database. If you need to target another database and program against a conceptual model (not a 1-1 mapping with your datatable structure and objects) you can have a look at LINQ to Entities.
