Steve Eichert reviews the book “TDD with .Net” , and seems to really like it. He also made something that I really appreciate - he wrote down a list of bullet points while reading the book, and then posted it. Even from such small points, you can still learn a lot, specifically about testing ADO.Net and web services.
Great Job Steve.
If you are working in a company where you are in charge of purchasing books, I suggest you get this book, if only to find out how test driven development can help your organization.
