is app.config file in WinForms cached by .Net framework?

问题

I was wondering if someone can confirm that App.Config file is cached by CLR in the AppDomain and not read everytime you try to read the value?

回答1:

It is loaded at start-up. Reads will reflect whatever the app.config file said at that point.
