Mastering Entity Framework Core 2.0

Introduction

The book "Mastering Entity Framework Core 2.0" (original title Mastering Entity Framework Core 2.0) by Prabhakar Acharya is a comprehensive guide to one of the key data access technologies in the .NET ecosystem. Published in 2017, it remains relevant for developers transitioning from classic Entity Framework 6 to the cross-platform Core 2.0 version. The book is 402 pages long and written in C#. It covers both basic ORM concepts and advanced techniques, from creating models to fine-tuning performance.

What This Book Is About

The author consistently guides the reader through all stages of working with Entity Framework Core 2.0. The narrative begins with installation and environment setup, then moves on to creating a data model, configuring relationships, using Fluent API and attributes. Much attention is paid to migrations — how to create, apply, and roll back database schema changes. Separate chapters are dedicated to LINQ queries, loading related data (Eager Loading, Explicit Loading, Lazy Loading), as well as working with transactions and concurrent access. The book concludes with sections on testing, deployment, and performance optimization.

Who It Is For

The book is aimed at developers already familiar with C# and the basics of .NET who want to deepen their knowledge of data access. It will be useful both for those transitioning from Entity Framework 6 to Core and for beginners starting with version 2.0. A basic understanding of relational databases and SQL is recommended for full comprehension of the material.

What the Reader Will Learn

• How to install and configure Entity Framework Core 2.0 in a .NET Core or .NET Framework project.
• Creating and configuring data models using attributes and Fluent API.
• Working with migrations: creating, applying, rolling back, generating scripts.
• Writing complex LINQ queries and using projections.
• Loading related data: Eager Loading, Explicit Loading, Lazy Loading.
• Managing transactions and handling concurrent updates.
• Testing code that works with Entity Framework Core (mocks, InMemory provider).
• Performance optimization: caching, connection pooling, query analysis.
• Deploying applications using EF Core in a production environment.

Strengths

The main advantage of the book is its practical focus. Each chapter contains numerous code examples that can be immediately applied in real projects. The author does not just list features but explains why to choose a particular approach and what pitfalls may arise. The chapters on migrations and performance deserve special mention — they are written in great detail and with real-world scenarios in mind. The book is well-structured: from simple to complex, with clear headings and a summary at the end of each chapter.

Who I Recommend It To

I recommend this book to all .NET developers who want to master a modern approach to working with databases. It will be useful both for self-study and as a desktop reference. If you work on projects where performance and flexibility of data access are important, "Mastering Entity Framework Core 2.0" will be an excellent investment of your time. Although the book was written for version 2.0, the core concepts and techniques remain relevant for newer versions of EF Core.
