Sending Property Value to Wix Extension Method

Question

I have a wix property

<Property Id="VAR1" Value="aValue" />

And i want to send this value into my Extension method

<Property Id="TEST" Value="$(extension.GetResult(VAR1)"  />

I want to send the value aValue into the GetResult method, but cant seem to find the correct syntax to convert VAR1 to 'aValue'

The extension is a preprocessor extension and the Property VAR1 will get set via the user interface...

Answer 1

Properties are only available at runtime, other than by parsing source itself.
