Entity framework 4 in action is an example-rich tutorial that helps .net developers learn and master the subject. It begins by explaining object/relational mapping and then shows how you can easily transition to ef from ado.net. Through numerous focused examples and two larger case studies, the book unfolds the ef story in a clear, easy-to-follow style. Infrastructure and inner workings of ef are discussed when you need them to understand a particular feature.
