I've just posted another round of updates to EF POCO Adapter based on feedback from users. This set of changes is focused on N-tier scenarios and detached entities (it adds missing wrappers for EF APIs and fixes behavior of existing ones).
The new release is here: http://code.msdn.microsoft.com/EFPocoAdapter/Release/ProjectReleases.aspx?ReleaseId=1580
Big thanks to everyone who sent me comments, bug reports and improvement suggestions for this release. This is very valuable feedback as it allows us to better understand user scenarios around POCOs for EF v2.
