By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J.

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:
