I think we can already handle that (see all the Qt ports). I'm not sure what currently happens when A depends on B and C but B and C depend on different versions of D.

In my ideal situation all dlls will be installed in the GAC (or just linked to where they are installed). If I read this [1] correctly, Debian advocates for all dlls to be registered in the GAC. > Another problem with nugets packages is that you only get binaries, > right?

This is my primary concern, how does one take control when each port manages its own private dependencies.
