If you are in the midst of learning about the ADO.NET Entity Framework, then you'll want to get the samples that I found on the CodePlex web site.
Initial samples for Entity Framework Beta 3: includes updated Getting Starting, NorthwindEF, and Query samples with three new sets of samples: Metadata, a WCF sample (MyTravel), and an Object Services ASP.NET sample. Most samples are available in both C# and VB.
