Book Description

December 1, 2011 1449312942 978-1449312947 1

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.

"It's a great cover-to-cover read, and I can easily see topics I'll bookmark and come back to when I hit certain scenarios. If you're planning on using EF Code First, make getting this book a priority." - John Papa, Visual Studio Magazine

5.0 out of 5 stars Quick and easy read, full of education January 5, 2012
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.

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 out of 5 stars 5 star read - but no index March 28, 2012
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 out of 5 stars Very well written June 11, 2013
Format:Paperback|Verified Purchase
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.

5.0 out of 5 stars Just the right book for CF February 5, 2013
Format:Kindle Edition|Verified Purchase
Very didactic and well explained. A good point is that the author does not forget about VB, giving good examples in both languages.

4.0 out of 5 stars Great side view of the Code First approach October 17, 2012
Format:Kindle Edition|Verified Purchase
Great overview for Code First, but to get whole picture of Entity framework you need to get to the main book "Programming Entity Framework: Building Data Centric Apps with the ADO.NET Entity Framework". Actually would be 5 stars if included unit-testing approaches.

5.0 out of 5 stars Outstanding, plenty of sample code November 30, 2011
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.

Julia is very thorough. She is an excellent teacher.
If there is anything I don't know how to do I can find the information very quickly in her book.
