I'd like to hear from people who are using EF in production, or made a valid attempt to do so.
I saw the When NOT to use the Entity Framework question on this site. I also read Vote of No Confidence. If you played with Entity Framework and decided not to use this, I don't want to hear from you.
I understand that EF is not mature as NHibernate or some other framework. Unfortunately, in my company, people who make decisions don't want to use the open source projects. Don't ask me why, because I'd like to know it myself.
