Where does IIS Express get its default applicationhost.config from?

Question

I added a couple of MIME types to the applicationhost.config files in C:\Program Files\IIS Express\AppServer and C:\Users\<me>\Documents\IISExpress\config\. But every time I launch IIS Express, it creates a new file in /Temp/IISExpress/ that doesn't have those MIME types.

Where is it getting that new file from?

FYI: I'm launching IIS Express via this VSCode plugin

Answer 1

Found it. There's another config file in C:\Program Files (x86)\IIS Express\AppServer
