In my previous posts on doing data access using LINQ and ASP.NET, I used the built-in SQLMetal command-line utility to automatically generate the data model classes for my LINQ data classes.   Recently, I have been using the LINQ for SQL (aka DLINQ) designer to define my data models and have been really impressed with how easily it enables me to build a re-usable class library that nicely encapsulates my data and business logic.

The below walkthrough demonstrates how you can get started with it yourself.  Simply install the LINQ May CTP download on top of VS 2005 and you can then follow all of the steps below yourself.  For the sample below I am using C#, but everything works equally well in VB.
