[cmake-developers] C# support?

[David Cole]

The C# compiler, csc.exe, takes all its arguments at once in one call
to build a library or executable. Listing all the sources, and its
references (other libraries it depends on) all at once. You can do it
as command line arguments, or as contents of a response file, or a
combination or arguments plus response file.

Conceptually, it's "just like Java."

They do have separate project files for it with VS, though. The
generators will need code to generate *.csproj files, rather than
custom commands in a vcxproj file, to make it seem like it's really
well-integrated with VS. Not sure if *.csproj files have evolved much
over the last few releases of VS -- I'd expect the major challenge
with this to be making sure CMake generates proper *.csproj files for
however many versions of VS it would take to make it acceptable.
