WIX HeatDirectory Task - Setting the preprocessorVariable

Question

I\'m trying to set the preprocessor variable in wix and i\'m unable to find an example of this or explanation on how to do it anywhere on the internet, i\'m hoping somebody

Answer 1

There is a $(HeatDefinitions) property you can set to define these in the parent .wixproj file:

      
        MySourcePath=..\src\Your.App\bin\Release 
    

    
        
        
    

    
        
    

The only existing mention of this magic property I can find (on the entire Internet) is in a single question about Team Build on the wix-users mailing list. I stumbled across it by luck after spending nearly a day tearing out my hair trying to fix undefined preprocessor variable errors.
