I have no idea. I write code only for VB languages. Your best reference is
the PIA documentation on MSDN; perhaps the example at
http://msdn.microsoft.com/en-us/library/bb608929.aspx will be helpful.

You should be able to use ItemProperties.Item("UID") or
UserProperties.Item("UID").

Thanks Sue that was the right hint to point me to a direction.
My code looks now like this, I guess the above only works for
VB.NET?
