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.

To get the most out of this book

This book assumes that you have some knowledge of C# (or a similar object-oriented programming language, such as Java) and that you have some experience in building web applications.

This book doesn't require any specific tools, but you will need .NET Core installed on your machine (https://dotnet.microsoft.com/download). I strongly suggest that you have at least one code editor, such as Visual Studio Code, possibly with OmniSharp, or an integrated development environment (IDE) such as Visual Studio (on Windows or Mac), or Rider IDE (on Windows, Mac, or Linux).

I've written all the examples on macOS X using Rider IDE and Bash.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The headers part tells the client that the response should be processed using a specific content-type; in this case, application/json."

A block of code is set as follows:

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFrameworks>netcoreapp3.0;net461</TargetFrameworks>
</PropertyGroup>
</Project>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFrameworks>netcoreapp3.0;net461</TargetFrameworks>
</PropertyGroup>
</Project>

Any command-line input or output is written as follows:

dotnet build
dotnet run

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "As you can see, it is running Hello, World!"
