Please see Mike's answer over at:

NSIS Changing config file present in XAP file i.e. silverlight component build

There's two parts here:

1) Authoring the Silverlight application to use an external config file.

2) Authoring your installer to update that config file. In this case of WiX, it's the XmlConfig element in the Util extension.

The reasons for doing it this way is to have a highly reliable installer. If you write custom actions to extract, edit and compress the XAP you'll invalidate digital signatures and introduce complexity and fragility to your deployment process. Avoiding the temptation to do all this and just use XmlConfig gives you a robust, declarative installation that fully supports the Windows Installer rollback story.

You could write a custom action to:

  1. Open the .xap file (it's a .zip file named differently)
  2. Extract the file(s) that need to be modified
  3. Edit the extracted file(s)
  4. Re-zip the extracted file(s) back into the .xap file.

You could find the existing .xap file using AppSearch of some sort. Maybe a FileSearch element. Most of the work is going to be in your custom action though. Good luck!
