Kind of a follow-on question: Once we've upgraded our developer PCs to VCVS2015 do we have to rebuild and deploy entire solutions or can we make changes and deploy individual projects (EXE or DLL) as needed?
In other words can a VC 2.3 VS 2013 COBOL native console EXE call a VC 2.3 VS 2015 COBOL native Link Library DLL on a CS 2.3 server?
