I love .Net
I recently made a demo of WCF and EF with POCO for French ALT .NET event.
Danny made a great demo for Tech Ed with EF, T4 generation template, WCF and ASP.NET MVC.
I now post a new EF and WCF demo that I made this week with DAL EF entities and BLL Entities.
EF4 will improve the use of EF with WCF but it isn't really a problem to use these two technologies together with EF v1.
