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.

Summary

The Catalog.Domain project now contains the core logic of the entire application. Although the logic implemented in the Domain project is still quite simple, later on in this book, it will become more complex.

The topics covered in this chapter included some of the concepts related to the domain logic implementation of a web service: how to implement the service and the mapping classes, how to implement the request validation process using a fluent approach, and finally, how to test our code using some unit testing techniques.

The next chapter will look into all the HTTP parts of the application. Furthermore, we will focus on the Catalog.API project, and how to put together the data access, the service, and the API layers.
