C# 7 and .NET Core: Modern Cross-Platform Development - Second Edition

Overview of this book

If you want to build powerful cross-platform applications with C# 7 and .NET Core, then this book is for you. First, we’ll run you through the basics of C#, as well as object-oriented programming, before taking a quick tour through the latest features of C# 7 such as tuples, pattern matching, out variables, and so on. After quickly taking you through C# and how .NET works, we’ll dive into the .NET Standard 1.6 class libraries, covering topics such as performance, monitoring, debugging, serialization and encryption. The final section will demonstrate the major types of application that you can build and deploy cross-device and cross-platform. In this section, we’ll cover Universal Windows Platform (UWP) apps, web applications, mobile apps, and web services. Lastly, we’ll look at how you can package and deploy your applications so that they can be hosted on all of today’s most popular platforms, including Linux and Docker. 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 Core.

Preface

Sharing code cross-platform with .NET Standard class libraries


Before .NET Standard, there was Portable Class Libraries (PCL). With PCLs, you can create a library of code and explicitly specify which platforms that you want the library to support, such as Xamarin, Silverlight, Windows 8, and so on. Your library can then use the intersection of APIs that are supported by the specified platforms.

Microsoft has realized that this is unsustainable, so they have been working on .NET Standard---a single API that all future .NET platforms will support.

If you want to create a library of types that will work across .NET Framework (on Windows), .NET Core (on Windows, macOS, and Linux), and Xamarin (on iOS, Android, and Windows Mobile), you can do so most easily with .NET Standard.

The following table summarizes versions of .NET Standard, and which platforms they support. Note:

  • .NET Core and Xamarin support .NET Standard 1.6

  • .NET Framework 4.6.1 already supports .NET Standard 2.0, but does not support...
