title: Visual Studio 2019 C++ and std::filesystem
body: <p>Now, I would have not expected That, after 'upgrading' to a 'newer' version of the compiler.</p>
  
  <p>In VS2017 std::filesystem was available through std::experimental::filesystem, Now after upgrading to VS2019 to my surprise it is not available at all. Not in std::experimental nor std::filesystem.</p>
  
  <p>and YES, I've tried setting c++17 from project's settings even the 'latest draft' thing, any ideas?</p>
