AutoMapper does not really compare to EF. AutoMapper is used to copy automatically data between two objects of different classes (like a.UtilisateurName = b.Utilisateur.Name). It uses Reflection for that. I will try to link automatically properties by their names. The two classes do not have to have the same format. It works if one the classes is the flattened version of the other.

It might not be really clear, sorry. Try to look on their website https://github.com/AutoMapper/AutoMapper/wiki/Getting-starte....
