The PR fixes the issue on my side.

I can confirm this issue exists on vs2019 using boost version 1.70.0. The above patch (https://github.com/codingdave/type_traits/commit/ff1a2967b3ca68a6f8fb229c5ad9bc2cfbeb2852) does fix the issue for me.

I have a similar issue. c++17, mcvs19, boost 1.73, x64.

include\boost\polygon\voronoi_builder.hpp(160,18): error C7626: unnamed class used in typedef name cannot declare members other than non-static data members, member enumerations, or member classes

couldn't solve it. rolling back to c++14.

@yoavmil That issue in Boost.Polygon was fixed in develop but not merged to master for the 1.74 release: boostorg/polygon@5cfcb6c

I'll merge it for the 1.75 release.

Great. thanks for the quick answer

The patch that @codingdave put up isn't quite correct. It will fix the issue for .NET Framework C++/CLI projects, but not for .NET Core C++/CLI projects.
