Sending XMPP message in Windows phone 8 does not require any analysis because it is a method built in with XMPP client of the DLL.
Below is the syntax required to be followed for sending message.
private void SendXmppMessage(String Message, JId ReceiverJid)
{
ObjXmppClient.SendChatMessage(Message.Trim(), ReceiverJid);
}
But to receive a message from other roster requires handler to initiate the message receiving asynchronously. The handler is OnNewConversationItem.

The syntax is mentioned below:

ObjXmppClient.OnNewConversationItem += ObjXmppClient_OnNewConversationItem;
void ObjXmppClient_OnNewConversationItem(RosterItem item, bool bReceived,TextMessage msg)
{
if (bReceived)
{
//do your property settings
}
}
If bReceived ==true, then message is received from other roster, or else message is sent by you to other roster.

hi the issue is you are clearing the connection properties while sending message "ObjXmppClient = new XMPPClient();" don't create new object while sending the message.
