Overview of this book

C# 7.1 and .NET Core 2.0 – Modern Cross-Platform Development, Third Edition, is a practical guide to creating powerful cross-platform applications with C# 7.1 and .NET Core 2.0. It gives readers of any experience level a solid foundation in C# and .NET. The first part of the book runs you through the basics of C#, as well as debugging functions and object-oriented programming, before taking a quick tour through the latest features of C# 7.1 such as default literals, tuples, inferred tuple names, pattern matching, out variables, and more. After quickly taking you through C# and how .NET works, this book dives into the .NET Standard 2.0 class libraries, covering topics such as packaging and deploying your own libraries, and using common libraries for working with collections, performance, monitoring, serialization, files, databases, and encryption. The final section of the book demonstrates the major types of application that you can build and deploy cross-device and cross-platform. In this section, you'll learn about websites, web applications, web services, Universal Windows Platform (UWP) apps, and mobile apps. By the end of the book, you'll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET.

Building mobile apps using Xamarin.Forms


We will build a mobile app that runs on either iOS or Android for managing customers in Northwind.

Note

If you have never run Xcode, run it now to ensure that all its required components are installed and registered.

Adding Android SDKs

To target Android, you must install at least one Android SDK. A default installation of Visual Studio for Mac already includes one Android SDK, but it is often an older version to support as many Android devices as possible. To use the latest features of Xamarin.Forms, you must install a more recent Android SDK.

Start Visual Studio for Mac, and navigate to Visual Studio Community | Preferences.

In Preferences, navigate to Projects | SDK Locations, and select the Platforms you want, for example, Android 8.0 - Oreo, as shown in the following screenshot:

Note

When installing an Android SDK, you must select at least one System Image to use as a virtual machine emulator for testing.
