[cmake-developers] 3.12.0-rc1: C# project outputting as a "vcxproj" (C++ project)

[Robert Dailey]

To fix this issue for now I had to do this:

        set_property( TARGET ${project_name} PROPERTY LINKER_LANGUAGE CSharp )

I don't remember having to explicitly tell CMake that the project is
CSharp in the past; it was always able to deduce it before. Is this
considered a symptom of a bug? Or is this required behavior? To be
honest, I'm not sure what criteria is used by CMake to deduce the
linker language of targets, especially in the C# case. It appears that
introducing a link-level dependency from a C# project to a Managed C++
project, forces the parent project to be C++ as well.
