I made a custom Redemption dll using customize.exe, as explained at
http://www.dimastr.com/redemption/security.htm. I changed all the class
names and GUIDs. Let's say my custom Redemption dll is called
MyRedemption.dll. All the class names are the same except I prepended
them with "My". All the GUIDs are unique and not the same as those of
the standard Redemption.dll.

I then decided to make a signed, primary interop assembly (PIA) for
what I consider to be a brand new COM dll that I originated. I called
my interop Interop.MyRedemption.dll.

I registered MyRedemption.dll ("regsvr MyRedemption.dll").

I registered Interop.MyRedemption.dll ("regasm
Interop.MyRedemption.dll").

In a C# project, I added a Reference to MyRedemption.dll by Browsing to
it. However, the end result of adding that reference was that
"Redemption" appeared in my project's list of references, not the
expected "MyRedemption".

I thought by making a custom Redemption dll, there was no connection
between my custom dll and Redemption.dll, but that appears not to be
the case. I conclude based on the results of my test that there are
some common GUIDs between my custom dll and the standard
Redemption.dll. Is that true?

Any suggestions?
