Mastering Entity Framework Core 2.0

By: Prabhakaran Anbazhagan

Overview of this book

Being able to create and maintain data-oriented applications has become crucial in modern programming. This is why Microsoft came up with Entity Framework so architects can optimize storage requirements while also writing efficient and maintainable application code. This book is a comprehensive guide that will show how to utilize the power of the Entity Framework to build efficient .NET Core applications. It not only teaches all the fundamentals of Entity Framework Core but also demonstrates how to use it practically so you can implement it in your software development. The book is divided into three modules. The first module focuses on building entities and relationships. Here you will also learn about different mapping techniques, which will help you choose the one best suited to your application design. Once you have understood the fundamentals of the Entity Framework, you will move on to learn about validation and querying in the second module. It will also teach you how to execute raw SQL queries and extend the Entity Framework to leverage Query Objects using the Query Object Pattern. The final module of the book focuses on performance optimization and managing the security of your application. You will learn to implement failsafe mechanisms using concurrency tokens. The book also explores row-level security and multitenant databases in detail. By the end of the book, you will be proficient in implementing Entity Framework on your .NET Core applications.

Prerequisites


.NET Core, the open source platform, paved the way for multi-platform support in Visual Studio 2017. The editors came in different flavors, supporting both platform-specific and cross-platform IDEs:

  • Visual Studio: An exclusive edition for Windows with Community, Professional and Enterprise editions:

Visual Studio 2017 IDE can be downloaded directly from https://www.visualstudio.com.

  • Visual Studio for Mac: An exclusive edition for macOS, which was actually inherited from Xamarin Studio (Xamarin was acquired by Microsoft):

Visual Studio for Mac can be downloaded from https://www.visualstudio.com/vs/visual-studio-mac/.

  • Visual Studio Code: The cross-platform editor from Microsoft for Windows, Linux, and macOS:

Download the desired version/edition of Visual Studio Code from https://www.visualstudio.com/downloads/.

The Visual Studio 2017 installer is segregated into workloads, individual components, and language packs. We will be installing and using Visual Studio Community 2017 with the workloads ASP.NET and web development and .NET Core cross-platform development. The workload is a combination of one or more individual components which can also be installed from the Individual components tab of the installer, as follows:

New Visual Studio installer with workloads 

We have looked at the different flavors/editions of Visual Studio available to us, and we will be using Visual Studio Community on our journey, which is free of charge for private and test purposes. It is up to the reader to pick an edition which suits their needs (the tools and scaffolding available in the IDE might differ).
