The ASP.NET team recently produced a great set of tutorials on creating web applications with the Entity Framework.  They guide you through the process of building an end-to-end working web application.  Topic covered include data-binding, sorting, stored procedures, validation, mapping, inheritance, and many others.

Each tutorial also contains downloadable samples in both C# and VB.  Check them out!
