Currently, 8 of the 10 videos on Code First and EF 4.1 I have already created for MSDN are online but they are not easy to find.

Three of them are on the msdn.com/data/videos page. The others have not been placed there yet although you can find links to the videos at msdn.com/data/ef and then from the videos to the articles.

Here are direct links to all of the videos and related articles that are currently online.
