I have an InstallShield project that builds fine in VS2019 and older but fails on VS2022. After removing and trying to add back the failing C++ content and primary output I find that the references to Primary Output and Content Files are missing from Files and Folders Visual Studio Solution section of VS integrated project. The two projects of the solution in question are legacy code from VS2010. The IS project compiles and builds in any version prior to VS2022, so it seems to be specific to this version of VS. Has anyone encountered this before? Did you find a cause and solution?
