Book Description
A Fluent Learning Book Based on the principles of cognitive science and instructional design, Fluent Entity Framework, part of the Fluent Learning series, is a true tutorial that will help you build effective working models for understanding a large and complex subject: developing Entity Framework applications using Visual Studio. Most introductory books just talk at you and give you “exercises” that have more to do with taking dictation than actually learning. Fluent Entity Framework is different. It guides you through learning the way your mind likes to learn: by solving puzzles, making connections, and building genuine understanding instead of just memorizing random facts. DETAILED INFORMATION ON HOW TO… • Write .NET applications using Entity Framework 5.0 • Use all three of the supported Entity Framework workflows • Create, extend, and query arbitrarily complex data models • Use the Entity Framework Fluent API and T4 templates to create truly provider-independent data models

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology There's a mismatch in the way OO programs and relational databases represent data. Entity Framework is an object-relational mapper (ORM) that bridges this gap, making it radically easier to query and write to databases from a .NET application. EF creates a data model that matches the structure of your OO code so you can query and write to your database using standard LINQ commands. It will even automatically generate the model from your database schema. About the Book Using crystal-clear explanations, real-world examples, and around 100 diagrams, Entity Framework Core in Action teaches you how to access and update relational data from .NET applications.
