I can't provide the full source at the moment. Suffice to say,
everything else is boilerplate code. The only changes that I'm making
to the entire assembly is within that entire method body I just
posted, and that's what makes it so confusing. Something like adding a
new interface implementation should be very straightforward, and yet,
PEVerify all of a sudden keeps complaining about it.
I figured out that the problem is caused by that one method, and once
I comment out that portion of the code that adds the interface
implementation, PEVerify works just fine again.
