Building RESTful Web Services with .NET Core

By: Gaurav Aroraa, Tadit Dash

Overview of this book

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs. The depth, breadth, and ease of use of ASP.NET Core makes it a breeze for developers to work with for building robust web APIs. This book takes you through the design of RESTful web services and leverages the ASP.NET Core framework to implement these services. This book begins by introducing you to the basics of the philosophy behind REST. You'll go through the steps of designing and implementing an enterprise-grade RESTful web service. This book takes a practical approach, that you can apply to your own circumstances. This book brings forth the power of the latest .NET Core release, working with MVC. Later, you will learn about the use of the framework to explore approaches to tackle resilience, security, and scalability concerns. You will explore the steps to improve the performance of your applications. You'll also learn techniques to deal with security in web APIs and discover how to implement unit and integration test strategies. By the end of the book, you will have a complete understanding of Building a client for RESTful web services, along with some scaling techniques.

Building the Initial Framework – Laying the Foundation of the Application

In the last chapter, we talked about REST, its characteristics, and how it is implemented in ASP.NET Core. We will go ahead with that knowledge and set up the environment to develop an application in this chapter.

We will start building the basic framework of the app. We will understand each and every HTTP verb, how they work, and their implementation paradigms in ASP.NET Core Web API. Before all that, we will have a quick look at SOAP and how it is different from REST.

While we walk though the verbs, we will explore a very easy-to-use tool to analyze the HTTP requests and responses.

We will cover the following topics:

  • All about web services (REST and SOAP)
  • Running the development server
  • REST verbs and status codes
  • Implementation of verbs in ASP.NET Core Web API
  • Examples using Postman
  • SOAP versus...
