Conventions used

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

Code in text: 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: “Kitty starts by creating an abstraction for what the builders will be producing – that is, the product. She creates an interface called IBicycleProduct.”

A block of code is set as follows:

public interface IBicycleProduct
{
  public IFrame Frame { get; set; }
  public ISuspension Suspension { get; set; }
  public IHandlebars Handlebars { get; set; }
  public IDrivetrain Drivetrain { get; set; }
  public ISeat Seat { get; set; }
  public IBrakes Brakes { get; set; }
}

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

namespace WheelchairProject;
public abstract class WheelchairComponent
{

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

$ dotnet build
$ dotnet run hillcrest
