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.

5.0 von 5 Sternen It's a Julie Lerman Book 12. August 2013
Format:Kindle Edition|Von Amazon bestätigter Kauf
Julie Lerman kann man durchaus als Autorität in Sachen Entity Framework betrachten. Wer Julie Lerman's Beiträge kennt, wird Ihren Stil in diesem Buch sehr schnell wieder finden. Das Thema Entity Framework im Code First Ansatz wird ausführlich (wenn auch nicht erschöpfend) anhand von realistischen Beispielen Stück für Stück durchgearbeitet und bietet eine solide Grundlage um eigene Gehversuche zu wagen. Alles in allem ein gut gelungenes Buch für EF Einsteiger und als Nachschlagewerk für Fortgeschrittene.

5.0 von 5 Sternen Quick and easy read, full of education 5. Januar 2012
Von James Skemp - Veröffentlicht auf Amazon.com
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.

5.0 von 5 Sternen Excellent tutorial/reference on modern EF development using Code First 25. Mai 2012
Von Björn - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I was initially quite skeptical about the content quality of this book, due to poor experience with programming EF 2ed;
However, this one is surprisingly well organized & well written, with extremely lucid explannations of key concepts using good examples. Well done!

5.0 von 5 Sternen 5 star read - but no index 28. März 2012
Von Mr. Matthew J. Caton - Veröffentlicht auf Amazon.com
Format:Taschenbuch
Just a quick note to point out this book has no index. It is however comparatively short and very well structured and hence its within reason to read it end-to-end. Until you have made it to the end however, the lack of an index makes it hard to just get on and code.
5 Stars none-the-less - its by Julia Lerman so would expect no less.

5.0 von 5 Sternen Very well written 11. Juni 2013
Von TJ - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Von Amazon bestätigter Kauf
I had previously tried to learn code first by using online examples and code that I had managed to collect. I did ok, but I had several questions. This book reminded me of why I should not learn from the web. It gives you the correct way to design your database using both Fluent API and and Annotations. From the start I was able to create each example as the book detailed. The only place that I had any trouble was with one to one relationships, and the book even stated that there would be some hangups with this. All these relationships took were a little bit of practice and I was well on my way to creating my own database using Code First. I have struggled with Code First for a while and it only took me a few weeks to get through this book and I feel like I am at the top of my game now. I would recommend this to anyone using C# development.

Again, if you want to know about EF this is a must read. Simple, but useful practice examples, all about a very exciting technology from M S
