Any good books to pick up for a well-rounded reference to Entity Framework 4?

Question

Hi guys. Been reading through Manning's NHibernate in Action book, and it has absolutely been terrific for laying out a good, solid, easy-to-digest (relatively) foundation on NHibernate.

Question is, are there any comparable [reference] books for MS' Entity Framework 4 as well? I'm feeling mighty biased for NHibernate right now, and that's probably 'cause I know a lot of its ins and outs as compared to EF4. Would probably be good to even out my references on the two subjects.

Answer 1

I can only speak of one, which is all i have needed so far:

Programming Entity Framework (2nd edition), by Julie Lerman.

Brilliantly structured, extreme detail (900+ pages), logical layout, plenty of examples.

The thing i liked is she built a real-world model later on the chapters, and gradually built upon that, applying different features of Entity Framework, as well as other related topics such as DDD, Repository, Unit of Work and TDD.

+1 to Julie Lerman - she rocks.
