Chapter 3. Putting Properties and AppSearch to Work
When using WiX, properties are the variables that store any temporary data during an install. As such, they provide definitions for various predefined and custom-made installer settings, store input from the user, and provide a means of transferring information from one task to another. Additionally, they can store the results of searching the user's computer for files, directories, registry keys, and settings.
In this chapter, you will learn:
The syntax for declaring and setting properties
How to reference properties in other parts of your markup
The built-in properties that Windows Installer sets for you
What AppSearch is and how to use it to search the end user's computer for installed components, registry keys, and so on
