ProbePresence Method
Use this method to probe for another entity's presence.
Syntax
[VB.NET] Public Sub ProbePresence(ByVal JabberId As String)
[C#] public void ProbePresence(string jabberId);
Remarks
In the case that the user needs to update a particular entity's presence this method can be used to retrieve it. After a successful call, the server will either respond with the last known presence for Jabber, or will send a presence element of type "error". In either case, the respond will be returned by a Presence event.
NOTE: This method has a corresponding asynchronous version (ProbePresenceAsync) for use in the Xamarin environment.
