The upthread "How did you generate this patch" question from Matthieu
still seems to apply. I.e.:

This context is something that's not there in the file on "master".

I really don't mind having some guide for VSCode in our developer
documentation, but I think if we (as a free software project) are
recommending proprietary software we should put that in some context
where we explain if/why it's needed, and if free alternatives are also
suitable.

I haven't used the VSCode integration you're documenting, but from the
diff and the "gdb" mention I gather that this isn't using some "native"
debugger of MSVC/VS's, but just using the VSCode editor as a wrapper for
gdb?

If that's the case wouldn't it suffice to link to some generic getting
started guide for debuggers? And e.g. recommend the GDB manual, maybe
there's a better online reference (I read it locally), but e.g.:
https://www.sourceware.org/gdb/current/onlinedocs/gdb.html

Then if we're recommending GUI wrappers those are a dime a dozen,
e.g. Emacs's GUD mode:
