Running Paraffin when building a wixproj

I've got a WiX project which pulls in a WiX Fragment with a load of supporting files.

I'm using Paraffin to build the wsx file for the fragment. At the moment I manually run a one line batch file to run with paraffin with the appropriate arguments whenever I make a change the supporting files folder.

Instead I would like paraffin to run as part of the build process. I'm guessing I need to add something to inside the .wixproj file, but I'm not actually sure what.

How do I do 开发者_如何学Pythonthis?

Found a solution:

  <Target Name="BeforeBuild">
    <Exec Command="paraffin -dir SourceDir -groupname MyGroupId -dirref MyDirId output.wxs"/>

  </Target>
