Should have included this info in the last post, but better late than never. 

If you have questions about EF4 beta 1, the place to ask is the EF4 pre-release forum:

http://social.msdn.microsoft.com/Forums/en-US/adonetefx/threads

If you are looking for the documentation, then you’ll be interested in this link to the MSDN online docs.  For beta 1 docs are only available online, but they will be available both online and offline by the time the EF4 & VS2010 ships.
