I keep on getting error squiggles on std::string_view, but I am able to build just fine. Is there a way to tell intellisense or the C++ linter to use C++17?
The specific error I get is:
namespace "std" has no member "string_view"
There's a posting in their GitHub issue tracker about this: std::string_view intellisense missing (CMake, VC++ 2017).
In another issue, it is said that the extension defaults to C++17, but does not yet support all of C++17 features: Setting C++ standard.
This is confirmed by c_cpp_properties.json Reference Guide, where an option is listed cppStandard which defaults to C++17. (To edit this file, press Ctrl + Shift + P and type in C/CPP: Edit Configurations).
It appears, then, they just don't have full support yet.
