Dependency Injection in .NET Core 2.0: Make use of constructors, parameters, setters, and interface injection to write reusable and loosely-coupled code

by Marino Posadas

Inject dependencies and write highly maintainable and flexible code using the new .NET Core DI Engine C# and .NET developers who have no idea what DI is and would like to understand how to implement it in their applications. .NET Core provides more control than ever over web application architectures. A key point of this software architecture is that it's based on the use of Dependency Injection as a way to properly implement the Dependency Inversion principle proposed in the SOLID principles established by Robert C. Martin. With the advent of .NET Core, things have become much simpler with Dependency Injection built into the system. This book aims to give you a profound insight into writing loosely-coupled code using the latest features available in .NET Core. It talks about constructors, parameter, setters, and interface injection, explaining in detail, with the help of examples, which type of injection to use in which situation. It will show you how to implement a class that creates other classes with associated dependencies, also called IoC containers, and then create dependencies for each MVC component of ASP.NET Core. You'll learn to distinguish between IoC containers, the use of Inversion of Control, and DI itself, since DI is just a way of implementing IoC via these containers. You'll also learn how to build dependencies for other frontend tool such as Angular. You will get to use the in-built services offered by .NET Core to create your own custom dependencies. Towards the end, we'll talk about some patterns and anti-patterns for Dependency Injection along with some techniques to refactor legacy applications and inject dependencies. Filled with examples, this book will take you through various techniques for injecting dependencies into your applications with or without the use of frameworks.
