As of the Microsoft .NET Framework 3.5 SP1, the ADO.NET Entity Framework is now available for application developers to build comprehensive data access solutions. This talk dives into the details of the Entity Framework with a look towards design and implementation considerations that one should apply. We take a scenario specific approach to walk through the building of N-Tier and Web Applications with the Entity Framework. We provide guidance for how to build applications today that can take advantage of future capabilities that we're planning. We also walk developers through some of the community releases that we've provided to help improve the development experience today.
