For the last two weeks I've had the opportunity to work on a project which uses Entity Framework (EF) ver. 1.0. For more than a year I've been reading complains, reviews and comparisons regarding EF but finally after using it I have my own opinion:

• It's not a mature solution.
• Definitely falls short when compared to other products in the same category, like NHibernate for example.
• It's not as bad as some people want to make it appear.
• Can help some teams deliver small projects on time, especially if the developers have no experience on the use of O/R mapping tools or if like in the project I was working on, most of the business logic was implemented on the database side.
