The resolution of that bug was that we now expose explicitly implemented interfaces automatically if there are no naming conflicts. But with COM it's usually a different story - the members should always just be there. Do the interop libraries use explicit interface implementation (if they did the method names would show up as something like Namespace.IFoo.Bar in ildasm)?
