>>>I am trying to clean up a project of all classes (vcx class libraries) that compiler pulls in. These class libraries that I am trying to remove (not delete because they belong to another project) not use by this project now but maybe in a way were used before. I want to take one .VCX file at a time and find how it gets pulled in. How would you do it? TIA.

No.

I know only that indirect references will prevent it.
