I found solution.
problem was simple. it was related with system locale of windows 10.
(so many time spent…)
my setting was korean, I also selected beta : Use Unicode UTF-8 for world wide language support combo box.(what I supposed to do? I don’t know…)
see this image.
that caused msbuild.exe make out of order.(command string is broken.)
shortly, uncheck combo box and reboot computer, I could build cuda samples…
ha…aa finally I can build cuda programs… yeah…
