I'm beginning a project in Xamarin.Forms C#, my environment is Visual Studio 2017 and a back end openfire server .
The main Feature is to create a chat app with private and public chat for Android, IOS and Windows phones.
The problem is here, I can not find a library or a tutorial to use the xmpp protocol with my actual environment.
I've been looking for an answer to my question for weeks now but I couldn't find anything on the internet.
Maybe you could give me an advice as a professional?
