I did just as documented at

I think Bojan's solution just to add .. is slightly better, because
the project root is indeed at .., and not where sln/vcproj are
located. The whole vc folder just enables convenient work in the IDE,
and strictly saying it isn't a part of project's source tree, so
people on Linux won't be forced to look there if they build the
project with gcc.

I did, but it doesn't work. VC still tries to open vc/main.cpp. I
checked this by putting an additional dummy main.cpp in vc.

Yes, I think this would help, but see above. Putting cross-platform
code in a folder named vc is a bit misleading, isn't it?
