There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "For example, if you need to use System.IO, you can get it from NuGet as a separate library, without the need to add and load the entire System assembly."

A block of code is set as follows:

public static IWebHostBuilder CreateWebHostBuiler(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>();

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

WebHost.CreateDefaultBuilder(args)
  .UseContentRoot(Path.Combine(Directory.GetCurrentDirectory(), 
   "/client"))
  .UseStartup<Startup>()
  .Build();

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

dotnet new web

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Open Visual Studio and go to File | New | Project...."
