Hi Val. I can't add anything useful to this sorry... except to say that i have really enjoyed using the DAL in my current project. I have no experience with others and have not done anything tricky like I have had to do in SQL server procs and what not. But it has made development easy for me.
So i hope it hasnt been abandoned :-) And i have spent a LOT of time in the book - extra examples and keeping that book up to date would be really helpful.
