What makes The ADO.NET Entity Framework different than other ORM in the market?

Question

The question header is clear, i want to know why its different and why, when to select it for my project?

Answer 1

I wrote a blog post on this a while ago. In short, it takes a fundamentally different approach to ORM than Hibernate, ECO, and the other ORMs that I have looked at. You may think this approach is better, worse, or unimportant, but if you look deep enough it's hard to dispute that it is different. But don't take my word on it. If you're really interested in this subject, I strongly recommend reading this technical paper and this interview in ACM Queue.
