Hi,

I am building this application that relies on SQL Server. I have created the setup project for the application itself, and creating a bootstrap setup to install sql server is missing. Now I need to figure out what the instance name is to pass that to my installer, so I can alter the appsettings.json file when installed so it point to the right sql server.

I also worry about when I get to the update scenario.. how do I manage the merge of existing appsettings with new potential changens when a user runs a installer for a newer version.

So... do I need a custom action in my basic installer? How do I pass a found instance name to it.. and if none...

I am not completely new to Wix, but far from the expert yet...

What I have tried:

My basic installer:
<?xml version="1.0" encoding="UTF-8"?>
