Ian Cooper has written a great article talking about LINQ to SQL and persistence ignorance, and his successes using TDD with projects using LINQ to SQL.
I don't normally link to someone else's post. Especially with such a great title. But what-the-heck, I've got nothing right now. Maybe I'll write something of my own while I'm slacking off at work tomorrow.
Of course, you realize Ian, I have to lampoon this ignorance stuff now. Its the Wayward way.
