Ron,
You need to use 'Explicit interface member implementations'.
http://msdn.microsoft.com/library/de...pec_13_4_1.asp
Your not really hiding the method of the interface, you are hiding the
implementation of the method. As you have found if you cast your object to
the interface itself, you can use the method.
Hope this helps
