using agsXMPP.Collections;
using agsXMPP.protocol.iq.roster;
using System.Threading;

namespace ConsoleApplication1

{
    class Program
    {

    {
        Console.WriteLine("Logged In");
    }

    {
        Console.WriteLine("Login");
        Console.WriteLine();
        Console.WriteLine("JID: ");
        string JID_Sender = Console.ReadLine();
        Console.WriteLine("Password: ");
        string Password = Console.ReadLine();

        Jid jidSender = new Jid(JID_Sender);
        XmppClientConnection xmpp = new XmppClientConnection(jidSender.Server);

        xmpp.Open(jidSender.User, Password);
        xmpp.OnLogin += new ObjectHandler(xmpp_OnLogin);


        Presence p = new Presence(ShowType.chat, "Online");
        p.Type = PresenceType.available;
        xmpp.Send(p);

    }


}

}

Your problem is that you need to wait OnLogin will be raised

xmpp.Open(jidSender.User, Password);
xmpp.OnLogin += new ObjectHandler(xmpp_OnLogin);

// Wait here

Presence p = new Presence(ShowType.chat, "Online");
p.Type = PresenceType.available;
xmpp.Send(p);

This article on codeproject.com has solution for this Creating a Jabber Client using the agsXMPP Library, not the best but it is good for start. 

bool isLoggedIn = false;
xmpp.OnLogin += (sender) => { isLoggedIn = true; };
xmpp.Open(jidSender.User, Password);

while (isLoggedIn == false) 
{ 
    System.Threading.Thread.Sleep(100); 
}

Presence p = new Presence(ShowType.chat, "Online");
p.Type = PresenceType.available;
xmpp.Send(p);
