Hands-On RESTful Web Services with ASP.NET Core 3

By: Samuele Resca

Overview of this book

In recent times, web services have evolved to play a prominent role in web development. Applications are now designed to be compatible with any device and platform, and web services help us keep their logic and UI separate. Given its simplicity and effectiveness in creating web services, the RESTful approach has gained popularity, and this book will help you build RESTful web services using ASP.NET Core. This REST book begins by introducing you to the basics of the REST philosophy, where you'll study the different stages of designing and implementing enterprise-grade RESTful web services. You'll also gain a thorough understanding of ASP.NET Core's middleware approach and learn how to customize it. The book will later guide you through improving API resilience, securing your service, and applying different design patterns and techniques to achieve a scalable web service. In addition to this, you'll learn advanced techniques for caching, monitoring, and logging, along with implementing unit and integration testing strategies. In later chapters, you will deploy your REST web services on Azure and document APIs using Swagger and external tools such as Postman. By the end of this book, you will have learned how to design RESTful web services confidently using ASP.NET Core with a focus on code testability and maintainability.

Dependency Injection System

Dependency injection is the basic building block of ASP.NET Core. This chapter shows how you can use dependency injection in order to resolve the dependencies of the classes inside an ASP.NET Core application. It also describes how you can deal with the dependency injection life cycle, and it provides some examples of how to keep the classes loosely coupled. The first part of this chapter will give you some basic theoretical ideas about dependency injection, while the second part will show you how to use it in any ASP.NET Core project.

This chapter will cover the following topics:

  • What is dependency injection?
  • Why implement the dependency injection pattern in real-world applications?
  • Overview of the dependency injection life cycle
  • How to implement dependency injections in ASP.NET Core
