Much has been written on the topic of ORMs and its failings. Most of the objections fall into two categories: Separation of Concerns and Object Oriented Design. For the Entity Framework we have good news for one these.
Developer Ricardo Peres of Portugal has published a seemingly unbiased comparison of the leading .NET ORMs: NHibernate and Entity Framework. While we recommend anyone considering both to read his article, Differences Between NHibernate and Entity Framework, we are going to tough on some of the key differences.
