title: Good Entity Framework sample applications?
body: <p>I am looking for some good asp.net sample applications which use Entity Framework. I saw a couple apps for NorthWind (one was MVC based). Looking for one with is more sophisticated than the simple apps at MSDN (HRSkillsCombined, CourseManager,AdWksSalesWinDataBind,  ResearchCollaborationAssistant). Possibly using Entity Inheritance, multi table change tracking.. etc.</p>
