Hello, the following fails on VS 2019

using microsecDouble = std::chrono::duration<double, std::micro>; auto microsecDoubleType = ::rttr::type::get();

with

When compiling with VS 2017, or with Linux, everything is fine. Any thoughts? Thanks,

just if this is like a showstopper:

you can use VS2017 compiled libs also with VS2019. This is since VS2015 the case.

Anyway the error should be removed.
