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. For example; "This can be achieved when we put some content into the DelegateCommand.cs file."

A block of code is set as follows:

private string _filePath;
private IFaceServiceClient _faceServiceClient;

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

private string _filePath;
private IFaceServiceClient _faceServiceClient;

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