Overview of this book

The C# programming language is often developers’ primary choice for creating a wide range of applications for desktop, cloud, and mobile. In nearly two decades of its existence, C# has evolved from a general-purpose, object-oriented language to a multi-paradigm language with impressive features. This book will take you through C# from the ground up in a step-by-step manner. You'll start with the building blocks of C#, which include basic data types, variables, strings, arrays, operators, control statements, and loops. Once comfortable with the basics, you'll then progress to learning object-oriented programming concepts such as classes and structures, objects, interfaces, and abstraction. Generics, functional programming, dynamic, and asynchronous programming are covered in detail. This book also takes you through regular expressions, reflection, memory management, pattern matching, exceptions, and many other advanced topics. As you advance, you'll explore the .NET Core 3 framework and learn how to use the dotnet command-line interface (CLI), consume NuGet packages, develop for Linux, and migrate apps built with .NET Framework. Finally, you'll understand how to run unit tests with the Microsoft unit testing frameworks available in Visual Studio. By the end of this book, you’ll be well-versed with the essentials of the C# language and be ready to start creating apps with it.

Using the .NET command-line interface (CLI)

The command-line interface (CLI) is a new but strategic tool in the .NET ecosystem, enabling a modern developmental approach that can be used the same way across all platforms. At first sight, defining a tool based on the old console as "modern" might look strange, but in the world of modern development, the ability to script the build process to embrace the Continuous Integration and Continuous Delivery/Deployment (CI/CD) strategy is fundamental to provide faster and higher quality development life cycles.

After installing the .NET Core SDK (see https://dotnet.microsoft.com/), the .NET CLI is available through the Linux Terminal or Windows Command Prompt. A good alternative on Windows is the new Windows Terminal application, which can be downloaded through the Windows Store and provides a great replacement for the traditional Command Prompt, as well as the PowerShell terminal.

The .NET CLI has a rich list of commands, enabling...
