Entity Framework - Code First CTP5 with Wouter Hendrickx
This talk 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.
Recommended resources for Entity Framework
A great resource for getting a hang of the Entity framework 4.1 is the ADO.NET team blog (http://blogs.msdn.com/b/adonet/). Specifically, the 12 post series titled “Using DbContext in EF 4.1” gives a nice overview of the features in CTP5.
Furthermore, Scott Guthrie’s blog contains a simple ASP.NET MVC demo, using the Code First approach for the data layer (http://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx).
The MSDN Data Development Center (http://msdn.microsoft.com/en-us/data) contains loads of information on EF 4.1 in its “Entity framework” section.
