Cu File cannot be compiled in VS 2017

I am having this is no matter in the NVIDIA cuda samples, new CPP project with correct Include, Lib import, and also a new CUDA runtime project.

The cu file is not recognize at all.

I just realized that my GPU is not CUDA-enabled. I searched for my NVIDIA GeForce 920MX here and it wasn’t found.

I am looking whether I can install CUDA toolkit on VS 2017. Because I tried multiple times and wasted 2 weeks without any improvement. It seems like not integrating well.
