Hi Chris,
Implemented Categories can be looked up in the registry properly,
instead of relying on Google, in HKEY_CLASSES_ROOT\Component Categories.
The GUID for generic .NET stuff is {62C8FE65-4EBB-45E7-B440-6E39B2CDBF29}.
I could not reproduce the issue you mentioned using 2.0.50727.4927 of
regasm.
Is this issue causing a technical issue? From what I can remember,
Implemented Categories are just stickers applied to components saying
"hey, I support XYZ group of interfaces if you need them". I don't think
they represent a guarantee of any kind (and therefore not relied
upon)... I could be wrong.
