Overview of this book

<p><span id="description" class="sugar_field">.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</span>.</p> <p><span id="description" class="sugar_field">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.</span></p> <p><span class="sugar_field"><span id="description" class="sugar_field">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.</span></span></p>

Preface

The main advantages of .NET Core


If we look at this framework from a more developer-like point of view, we could say that what makes .NET Core different from other choices can be summarized in the following points:

  • Cross-platform: This means execution on Windows, macOS and Linux, and also its portability to other operating systems. You can check the list of supported operating systems on various sites, such as https://github.com/dotnet/core/blob/master/roadmap.md, and you should bear in mind that CPUs and application scenarios will keep growing, whether they are provided by Microsoft or other companies.
  • Compatibility: .NET Core is not only compatible with the .NET Framework, but also with Xamarin and Mono, thanks to the .NET Standard Library. As the official documentation states, the .NET Standard Library is,

"a formal specification of .NET APIs that are intended to be available on all .NET runtimes. The motivation behind the Standard Library is establishing greater uniformity in the .NET ecosystem...
