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.

Understanding NuGet packages


.NET Core is split into a set of packages, distributed using a Microsoft-defined package management technology named NuGet. Each of these packages represents a single assembly of the same name. For example, the System.Collections package contains the System.Collections.dll assembly.

The following are the benefits of packages:

  • Packages can ship on their own schedule
  • Packages can be tested independently of other packages
  • Packages can support different OSes and CPUs
  • Packages can have dependencies specific to only one library
  • Apps are smaller because unreferenced packages aren't part of the distribution

The following table lists some of the more important packages:
