I have an assembly in VB.Net that has a single ComClass in it to allow
existing VB6 applications to use it.

I've recently had to upgrade it to VS 2005 and in doing so found more
classes in the assembly now appear to be visible to COM.

To counteract this I have set all .Net classes and assembly to
ComVisible(false) leaving just the ComClass visible.  This all seemed to work
without any problems but when I examined the class through the object browser
in VB6 I noticed that an enum included in the ComClass did not appear and
that methods that used the enum did not appear.

Playing around I found that I could get the enum to appear if I made the
assembly ComVisible but that led to other classes also being displayed (web
references).

Does anybody know why the enum doesn't appear when the assembly has
ComVisible(false) and is there a way to resolve the problem?
