I made a round of updates to the EF FAQ a while back but then had some trouble with the blog software (it doesn't really like the huge word doc chunks I cut and paste into it) and didn't get around to fixing things. This morning I gave it another go and things worked. So we finally have a few updates. You can take a look at: http://blogs.msdn.com/dsimmons/pages/entity-framework-faq.aspx
I have a whole queue of topics that I need to add or update on the FAQ and will get to them as soon as I reasonably can, but I've been focused on development work for the next release of the EF (which will ship with VS 2010/.net 4.0) and haven't had the cycles I would have liked to devote to this. As always, if there's someone out there who would like to contribute to the FAQ, please let me know.
