WiX Project Reference Variables

Once a project reference is added, a list of project variables becomes avaliable to be referenced in the WiX source code. Project reference variables are useful when you do not want to have hard-coded values. For example, the $(var.MyProject.ProjectName) variable will query the correct project name at build time even if I change the name of the referenced project after the reference is added.
The following demonstrates how to use project reference variables in WiX source code:

Variable name	Example usage	Example value
var.ProjectName.Configuration	$(var.MyProject.Configuration)	Debug or Release
var.ProjectName.FullConfiguration	$(var.MyProject.FullConfiguration)	Debug|AnyCPU
var.ProjectName.Platform	$(var.MyProject.Platform)	AnyCPU, Win32, x64 or ia64
var.ProjectName.ProjectDir	$(var.MyProject.ProjectDir)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MyProject\
var.ProjectName.ProjectExt	$(var.MyProject.ProjectExt)	.csproj
var.ProjectName.ProjectFileName	$(var.MyProject.ProjectFileName)	MyProject.csproj
var.ProjectName.ProjectName	$(var.MyProject.ProjectName)	MyProject
var.ProjectName.ProjectPath	$(var.MyProject.ProjectPath)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MyProject\MyApp.csproj
var.ProjectName.TargetDir	$(var.MyProject.TargetDir)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MyProject\bin\Debug\
var.ProjectName.TargetExt	$(var.MyProject.TargetExt)	.exe
var.ProjectName.TargetFileName	$(var.MyProject.TargetFileName)	MyProject.exe
var.ProjectName.TargetName	$(var.MyProject.TargetName)	MyProject
var.ProjectName.TargetPath	$(var.MyProject.TargetPath)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MyProject\bin\Debug\MyProject.exe
var.ProjectName.Culture.TargetPath	$(var.MyProject.en-US.TargetPath)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MyProject\bin\Debug\en-US\MyProject.msm
var.SolutionDir	$(var.SolutionDir)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MySolution\
var.SolutionExt	$(var.SolutionExt)	.sln
var.SolutionFileName	$(var.SolutionFileName)	MySolution.sln
var.SolutionName	$(var.SolutionName)	MySolution
var.SolutionPath	$(var.SolutionPath)	C:\users\myusername\Documents\Visual Studio 2010\Projects\MySolution\MySolution.sln
