Why does the compiler say my execution policy is undefined?

I'm trying to do a parallel STL sort but I get a compiler error when I specify the execution policy:
1>c:usersdavemcdocumentsgpu-ray-traversal-cudasrcrttesttestcpp.cpp(14): error C2039: 'execution': is not a member of 'std'
I am including and in the GUI I see items from the execution namespace listed as possible completions of "std::". I am using Visual Studio 2017 version 15.8.9, which supports execution policies.
Here is my code:
#include <vector>
#include <execution>
#include <algorithm>
void testHostSort(size_t N)
{
std::vector<float> a(N);
std::generate(a.begin(), a.end(), () {return (float)rand(); });
std::sort(std::execution::par, a.begin(), a.end());
}

Are you compiling with/std:c++17or/std:c++latestswitch? Otherwise it defaults to C++14

I wasn't. Thanks for that. However, I just added /std:c++latest and rebuilt all but I'm getting the same result.

Cannot reproduce, it works fine with the switch enabled: godbolt.org/z/tLd_C7

I try it in an isolated project and it works, as you point out, but it doesn't work as part of my whole codebase. I wonder what I'm missing.

Could be various things: Something overwriting your C++ standard setting, maybe the project is targeting an older Windows runtime that doesn't support C++17 execution policies. However it's not related to the code, but your project settings
