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.

Adding a .NET Standard 2.0 library to the Xamarin project

In this recipe, we will be looking at creating a .NET Standard 2.0 library and moving the default count code into the library. The counting code was created by Visual Studio for Mac as a default template for the Android app.

Getting ready

Make sure you have completed the previous recipe that creates a default Android Application. If you have already completed it, let's open up that solution and get started.

How to do it...

Open Finder.
Click Applications in the left-hand pane.
Now, double-click on the Visual Studio icon.
Click on Open, locate the Chapter9.Xamarin solution, and open it.
The Solution Explorer should look like this:

Now, control (^) + click on the Chapter9.Xamarin label and select Add | New Project.
In the New Project dialog box, scroll down the left-hand pane until you see the Multi Platform section.

Click on Library and select .NET Standard Library under General in the right-hand pane. Also make sure C# is selected:
