I've been looking at various different ways of making an installer (see How to create a robust, minimal installer for Windows? for details), and I've run into the same thing in a couple of them (WiX and the visual studio installer creator); there doesn't seem to be a way to say "When you build the installer, include every file matching c:\somefolder\*.xml".
I can go and select *.xml and add all the files that match to the project at once, but then if I add another .xml file to my program later, I'd need to go and add that to the installer myself.
Is this a core limitation of windows installer, that I can't just tell it "sort all the XML files in this folder out and don't bother me about them"?
