Hello,
in the Office 2007 beta 2 typelib, IRibbonExtensibility is a dual interface,
and so is AddInDesigned::IDTExtensibility2. As far as I can tell, an add-in
has to implement both because it is first loaded with IDTExtensibility2 and
then the same object is QI'd for IRibbonExtensibility. Implementing both as
dual interfaces is impossible - the two interface's dispids clash. Even if
they would not, implementing a single IDispatch with both interfaces' dispids
is hard on the implementor, because there is no attributed support for it.
Of course it currently works, because Office does not call on the IDispatch
interface. So why require it then?
