Kurzbeschreibung
Take advantage of the Code First data modeling approach in ADO.NET Entity Framework, and learn how to build and configure a model based on existing classes in your business domain. With this concise book, you'll work hands-on with examples to learn how Code First can create an in-memory model and database by default, and how you can exert more control over the model through further configuration. Code First provides an alternative to the database first and model first approaches to the Entity Data Model. Learn the benefits of defining your model with code, whether you're working with an existing database or building one from scratch. If you work with Visual Studio and understand database management basics, this book is for you. * Learn exactly what Code First does-and does not-enable you to do * Understand how property attributes, relationships, and database mappings are inferred from your classes by Code First * Use Data Annotations and the Fluent API to configure the Code First data model * Perform advanced techniques, such as controlling the database schema and overriding the default model caching This book is a continuation of author Julia Lerman's Programming Entity Framework, widely recognized as the leading book on the topic.

Quick and easy read, full of education
5. Januar 2012
Format:Taschenbuch
While I had heard of Julie Lerman and her book Programming Entity Framework, after the release of code first I was on the fence on just how much I would get out of the existing book. With the release of Programming Entity Framework: Code First I knew I'd learn something, so I picked up an electronic copy (PDF) and started digging in.
First, I should mention that I initially started working with Entity Framework via existing databases. I tried the pre-4 version, but ultimately tried to stay away until EF4 was released. I liked the Visual Studio interface to work with a database via EF, and created one site, still in production, that uses it, but I like being closer to the metal.
With the release of EF Code First I started digging in immediately, using it to create functionality on one site already in production, and most recently started working on another site, for eventual release into production. However, on this latter site I was working with more advanced models and kept running into weird EF issues.
After a few chapters in Programming Entity Framework: Code First I had determined what my issue was, and how to fix it, which alone is worth the price. In addition, while I understood data annotations, I now have a pretty firm grasp on what I can do via the Fluent API, and how I can better control what EF does when it creates the database to store my model.
The size of the book may initially throw you off, but I honestly believe that this book contains as much material as a book almost twice the size. In addition, while I came into the book having already worked with Entity Framework, and code first, I believe this book can easily be picked up by someone new to both technologies. Also, while the 'first' book is referred to within this book, having read it is not necessary.
Julia Lerman will be releasing another book, Programming Entity Framework: DbContext, and I will honestly be picking that book up as well. At this point, however, I'm still on the fence on whether I'll be picking up the 'primary' book, Programming Entity Framework, but I'm sure at some point I will, as I believe it will still be beneficial.
This book will definitely have select chapters read again, and will serve as a good reference, so I give this book 5 of 5 stars.

Outstanding, plenty of sample code

This book and the 2nd Edition of Programming Entity Framework by this author gave me all the foundation I needed to begin using EF in a very smart and efficient manner in real production projects. Code First taught me how to keep my POCO classes completely free of data annotations and use the powerful fluent API to configure all the mappings and attributes needed to match my classes to the database table by using configuration classes in code. This is the central reason I chose to use Code First.
The foundation provided in the previous book made learning Code First easy. I learned what choice to make from the possibilities and what the benefit and compromise of that choice were.

So Impressed I bought the next Book as Well

Format:Taschenbuch
Have been using Entity framework in a very basic config for a while. Being previously a very HEAVY Db implementer I have been watching ORM's coming down the pipe for a while. I could not believe how easy to ready & learn from this book was
It just absolutely clicked with me & the technology. I smashed the entire book & examples in 3 days.
From 0 to 6-7 out of 10 in such a short time frame has been great !!!!
Has turned this technology set into my new favourite & also went & got the DBContext book as well. Cant wait to crack it open.
To the Authors so clear,consise, easy to read thats walks u through the creation of a complete working example with the mini tasks.
Too Good :)
