Mastering Entity Framework Core 2.0

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.

Installing Entity Framework


The Entity Framework package should be installed as part of the NuGet package, and can be done in the following ways:

  1. Go to the Package Manager Console (Tools | NuGet Package Manager | Package Manager Console), select the project where the package should be installed:

Add the following command in the PM Console to install the package on the selected project:

  Install-Package Microsoft.EntityFrameworkCore.SqlServer

The Package Manager Console will be opened as shown in the following screenshot, Kindly use this space to install the package using the preceding command:

PM console

  1. Go to the Package Management tab (either from Tools or from Dependencies/Project).
    • For a solution-wide installation, and availability for all projects that are part of the solution, go to Tools | NuGet Package Manager | Manage NuGet Packages for Solution... or right-click on the solution from Solution Explorer and select Manage NuGet Packages for Solution...
    • For project wise installation, right-click on dependencies from the desired project or right-click on the desired project and select Manage NuGet Packages...
  1. Search for Microsoft.EntityFrameworkCore.SqlServer, select the stable version 2.0.0 and install the package. It contains all the dependent packages as well (key dependencies such as System.Data.SqlClient and Microsoft.EntityFrameworkCore.Relational):

We have looked at different ways of using the Package Manager console so far, and installed packages related to EF Core. In the next section, we will start building the schema and later consume the created entities using EF.
