You can develop and deploy C# and .NET apps using Visual Studio Code and the command-line tools on most operating systems, including Windows, macOS, and many varieties of Linux. An operating system that supports Visual Studio Code and an internet connection is all you need to follow along with this book.

If you prefer alternatives, then the choice is yours whether to use Visual Studio 2022, or a third-party tool like JetBrains Rider.

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example: “The Controllers, Models, and Views folders contain ASP.NET Core classes and the .cshtml files for execution on the server.”

A block of code is set as follows:

// storing items at index positions 
names[0] = "Kate";
names[1] = "Jack"; 
names[2] = "Rebecca"; 
names[3] = "Tom";

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are highlighted:

// storing items at index positions 
names[0] = "Kate";
names[1] = "Jack"; 
names[2] = "Rebecca"; 
names[3] = "Tom";

Any command-line input or output is written as follows:

dotnet new console

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes. For example: “Clicking on the Next button moves you to the next screen.”
