This video presents the new developments in Entity Framework. More specifically, the EF 4.1 features involving "Code First" are discussed.
The session first gives an overview of the state-of-the-art Entity Framework approach using the EDMX model. It pinpoints some of the weak points of this approach and provides some context.
Then, the "Code First" approach is introduced using an example data model, both the fluent interface and attribute way of configuring the code first context are presented, and some example usage of the code first POCO's is given.
The presentation concludes with a more exotic setup involving multiple EDMX files with navigation properties linking them together.
