BitMono Combo
BitMono alone isn’t the whole story. Its packers are genuinely good at keeping dnSpy and other popular tools from even opening your file :D but for serious protection you’ll still want another layer on top of what BitMono does today.
The trick is the order: run the other tools first, and BitMono last. So a typical combo looks like:
ConfuserEx
any other tools you have and want to use
BitMono (last)
That way BitMono’s packers wrap up everything the earlier tools produced.
