I'm updating an old addin (12-ish years old) from a different code base to C#.
For the original codings, we used either a config.ini file and/or a series of XMLs and constants classes to reference multiple use things like button labels, names of tables, feature layers, data views, etc that we'd use and re-use.
Is there any equivalent way to do this for Pro? I've read about managed configurations, but I don't think that's what our client is going to want.
