When ContactCardCompleted occurs, did you check e.Error ?

If e.Error is not null, ContactCard is null. Some users haven't contact card.

ContactCardCompletedHandler never gets called.
The exception is thrown inside the MSNPSharp, and i cannot catch it and move-on.

So basically i call "contact.GetContactCard(contact.Mail)" and MSNPSharp blows 
up.
and I tried to put try/catch arounf GetContactCard, and no luck.

Here is my code ContactCardCompletedHandler code:
----------------------
        private void ContactCardCompletedHandler(object sender,
ContactCardCompletedEventArgs e)
        {
            try
            {
                String email = "";
                if (e.ContactCard != null)
                {
                    email = e.ContactCard.Mail;
                }
                TraceMessage("ContactCardCompletedHandler, " + email);
                if (email.Length != 0)
                {
                    ...
                }
            }
            catch (Exception ex)
            {
                TraceException("ContactCardCompletedHandler", ex);
            }
        }

Here is the code and stack-trace (attached as files)

i think its a particular contact that is a corner-case here.

cause i am avoid those null contact occurences...

i just want to be able to catch this corner case and move on..

thanks

I found the issue:

This:

e.Result.GetXmlFeedResult.contactCard.elements.element 

is null

here is the offending code is MSNPSharp:

foreach (elementType element in 
e.Result.GetXmlFeedResult.contactCard.elements.element)
{
...
}
