Entity Framework 4 in Action is an introduction to the Entity Framework for developers working in .NET who possess a working knowledge of ADO.NET. Beginning with a review of the core ideas behind the objectrelational management (ORM) model, it outlines how Entity Framework offers a smooth transition from a traditional ADO.NET approach. Featuring numerous examples and in-depth case studies, the book explores the Entity Framework story in clear, easy-to-follow detail. The infrastructure and inner workings are highlighted as needed and where they relate to particular features. This book clearly explains what Entity Framework can do for the reader, without getting sidetracked in the theoretical details of implementation. It is an ideal resource for the developer who needs to implement a solution using Microsoft technologies and has made the decision to use the Entity Framework.
