Defining Wix properties and values based on VS active configuration

Question

How can I define Wix properties and values that change depending on which Visual Studio configuration is active? e.g. For our release build, var x = 1 and for the export build,

Answer 1

I am using WiX 3.10 and $(var.Configuration) just worked for me.

Answer 2

You can use Project Reference Variables for that. No need to specify constants.

Sample steps:

1. Add a project reference (of the application) to your setup project

Right Click 'References', 'Add References'

2. Use project reference values in your wxs file

$(var.ProjectName.Configuration)

<?if $(var.ProjectName.Configuration)  = Debug ?>
  <?define x=1 ?>
<?endif ?>

Answer 3

We pass properties into WiX from the wixproj files using

<DefineConstants>configuration=$(Configuration)</DefineConstants>

In a PropertyGroups section. Then you can use them inside wix as $(var.configuration)

<?if $(var.configuration) = Debug ?>
  <?define x=1 ?>
<?endif ?>

The WiX help file has a whole section on preprocessor stuff, give that a look for other things you can do.
