The official source of information on Managed Providers, DataSet & Entity Framework from Microsoft
We’ve created a Camtasia™ video, available here, demonstrating some of the features of the Entity Data Model Designer. This video was just shown at VSLive in Las Vegas and demonstrates some of the mapping capabilities of the tools and runtime, including entity splitting and a mix of table-per-hierarchy and table-per-type mapping strategies. We also show a basic example of extending generated code using partial classes, LINQ, and associations.
As a bonus, since this demonstration is on a very early CTP2 build, you even get to see some of the UI updates we’re doing to support stored procedures.
