Sharp.Xmpp is looking for a maintainer! Unfortunatelly I do not have currently the time needed to maintain the library. Luckily a small but vibrant community has evolved around Sharp.Xmpp. If you would like to be the project's maintainer please sent an email to pgstath@gmail.com. This should include issues, tickets and commits that you have done for Sharp.Xmpp or other similar project. Sharp.Xmpp is a multiplatform, Windows and Android, .NET XMPP client assembly.Sharp.Xmpp supports IM functionality & a variety of XMPP extensions, is simple and is extensively tested against Android Xamarin. It is a fork of the currently frozen excellent S22.Xmpp project. Sharp.Xmpp will be at the FOSSDEM 2016 Real time DevRoom!

TargetInvocationException on XmppIM Constructor #43
I'm having a TargetInvocationException when instantiate the XmppClient.
Can someone help?
Here the code I created:
var client = new XmppClient("host.com");client.Message += delegate(object sender, MessageEventArgs args){OnMessage?.Invoke(this, new XamarinForms.XMPP.MessageEventArgs{Message = args.Message.Body,TimeStamp = args.Message.Timestamp,UserId = client.Jid.Node,});};client.Authenticate("myuser", "password");
Error occurs in this line of the XmppIM constructor:
core = new XmppCore(hostname, port, tls, validate);
And thats the stack trace:
