Fighting a strange problem. A Missing Member Exception is raised when I
try to call an interface method in the concrete class. However, the
project compiles just fine. Anyone run into this? Any ideas on how to
get around this?
More details:
-IMyDBServices interface
-MyDBServices implementation of IMyDBServices interfaces
-MyBusObj class implements IMyDBServices interfaces. The interface in
question is IMyCollection, which has two overloads defined for Remove,
one that takes a integer and one that takes an IMyItem interface.
All of the above are C#. The GUI is VB.NET. When the code in the GUI
tries to call IMyCollection.Remove(), passing an interface, the
MissingMemberException is raised. The strange thing is that the stack
trace indicates that VB is doing some late binding.

The actual error message is:
"Public member 'Remove' on type 'CoNameCol' not found."
One other note, the business object variable is declared as type
IMyCollection, then instantiated as MyBusObj.
Thanks for any ideas.
