Question

I have to create a set up file for a client app for LIVE/QA/UAT environments and the only difference between them is the app.config file. Can you please suggest an easy way to accomplish it?

Answer 1

A good approach is modifying a template app.config based on user input:

• configure your app.config file to use installer properties: http://wix.sourceforge.net/manual-wix2/wix_xsd_xmlfile.htm
• create some custom dialogs which retrieve the element information from the user and save them in your custom properties
