I have a solution with many projects; I would like to have a shared configuration (for example all have the same connection string). During deployment I don't want to make the same modifications in 10 places.
To make matters worse the development folders (bin\Debug\netcoreapp3.1) differs from deployment so that I cannot create a file in a relative path.
Edit: Of course I could just create a config file on a fixed path (ex /etc/MyApp/config.json (linux) or c:%appdata%\MyApp\config.json (win) (or a registry entry)
