Conventions used

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

CodeInText: Indicates code words in text, class names, property names, field names, folder names, filenames, file extensions, pathnames, URLs, and user input. Here is an example: "Create a new folder in the core project named Models."

A block of code is set as follows:

public abstract class BaseViewModel
{
    protected BaseViewModel ()
    { } 
}

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

public App()
{
    InitializeComponent();
    MainPage = new NavigationPage(new TripLog.MainPage());
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "In Visual Studio, click on File | New Solution."
