POCO Support in the Entity Framework

While the application I am developing at the moment is written in .net 4.0 against the beta, I have largely been ignoring POCO support in the Entity Framework because I didn't need it. I'm starting to realize, however, that POCO support would be useful in my project. However, Google searches on POCO in the EF yield a lot of results about it "coming in the 开发者_运维百科future" and "sneak peeks."

With the .net 4.0 framework in a Go Live license now, I know that POCO support must be largely implemented. Can anyone point me to a good resource for getting my feet wet on how it all works?

Julie Lerman has several blog entries on EF 4 POCO.

Another source for information (besides Julie Lerman's blog) is the ADO.NET team's blog, e.g:
