I think this OS and language runtime dependent @Artyom Slesarenko . I wasn't able get it a new line to show up on a Linux app running PHP or dotnet. I also attempted a test variable in my WSL instance and wasn't able to get \n
to be recognized as a new line.
What did work however, at least in .NET 7, was using an app configuration reference. This is a viable option if all you're doing is setting a app setting.
