In Detail

Entity Framework 4.1 allows us to dive into the world of data access without having to write SQL statements. With the power to shape data access by your object model comes questions and this book holds the answers.

Entity Framework 4.1: Expert’s Cookbook holds many examples to help guide you through tough technical decisions and avoid technical landmines. The book will guide you from just using Entity Framework to enhancing the data access wizard.

This book starts with examples that require some familiarity of object relational mappers, and then moves on to more advanced tasks. You will be guided through complex mapping scenarios, query definition, reusability, integration with other technologies, and architectural management. The approach is step-by-step and test driven so that it is focused as much as possible on solving problems and getting the most out of the time spent working through the book.

Entity Framework 4.1: Expert’s Cookbook is a must have for any .NET developer who uses Entity Framework, and wants better, cleaner, and more maintainable code.
