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. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The details of spatial reasoning are encapsulated in the HolographicFrame class, which is created at each frame within the Update method, as in the following extract." 

A block of code is set as follows:

 public HolographicFrame Update()
 {
 // ...
 HolographicFrame holographicFrame =  
 holographicSpace.CreateNextFrame();
 // ...
 }

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 void SetHolographicSpace(HolographicSpace holographicSpace)
{
// ...
referenceFrame = locator.CreateStationaryFrameOfReferenceAtCurrentLocation();
} 

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Next, launch Visual Studio, and create a new project by selecting the File | New Project menu item."
