I was paying attention to your post as I have seen that before but failed
to recall how I resolved it. I assure you the CA project does not need to target
3.5, that simply resolved your issue somehow but it is not a requirement.

I am currently in working in a large project with countless CAs and the solution
is targeting 4.6.2.
