Hi Ann,

I am afraid currently Visual Studio 2005's code analysis tool doesn't
provide such a feature to enumerate all the classes in a solution/project
to indicate which ones are never created or referenced.

I also perform some research on this issue, but unable to other third-party
to do this. I suggest you can submit this feedback to our product feedback
center, our development team may communicate with you directly on the issue
there:

Thanks!

Best regards,
