How LINQ to Dataset works in VB (Jonathan Aneja)

Recently I got a customer question about how to use LINQ to Dataset in an .aspx file.

This post assumes you’ve read my previous Converting SQL to LINQ posts. I haven’t had much in the way of specific requests for more LINQ posts, so I’d still welcome any suggestions that people want to offer.
