Overview of this book

The .NET Standard is a standard that represents a set of APIs that all .NET platforms have to implement, making it easy for developers to access and use one common library for their development needs. This book begins with a quick refresher, helping you understand the mechanics of the new standard and offering insight into how it works. You’ll explore the core library concepts, such as working with collections, configurations, I/O, security, and multithreading. You’ll explore the iOS and Android libraries of Xamarin and we’ll guide you through creating a .NET Standard 2.0 library, which you’ll use with both Android and iOS applications. In the final chapters, you’ll learn the various debugging and diagnostics tools to deliver quality libraries and create a NuGet package of the .NET Standard 2.0 library. By the end of this book, you’ll be able to expand your current workflow to various .NET flavors and have the essential skills to create a .NET Standard 2.0 library from scratch to package and deliver it to the world.

Creating a library to call a REST API


In this recipe, we will be looking at a .NET Standard 2.0 library that calls a REST API. RESTful APIs are services that allow you to access its functionality through HTTP. We will be using the System.Net.Http namespace inside the library to send a message to an API and get back the results.

Getting ready

Make sure you have the latest version of Visual Studio 2017. Also make sure you have a basic understanding of accessing a web service, what a GET method is, what a POST method is, and so on. We will be using a test API service provided by JSONPlaceHolder. It's a simple REST API test bed for developers.

How to do it...

  1. Open Visual Studio 2017.
  2. Click File | New | Project to create a project. 
  3. In the New Project dialog box, expand the Other Project Types node in the left pane and select Visual Studio Solutions. In the right pane, select Blank Solution.
  1. In the Name: textbox, type Chapter7.RestAPI and in the Location: textbox select a path from the drop-down box...
