compile using msvc /clr

I'm using VS 2019 and msvc. I need to compile boost using /clr switch since a project that I need to reference in a C# project uses boost. Is this possible. So far I can't get it to work using msvc-14.2 e.g. b2 --toolset=msvc-14.2

project-config.jam
using msvc : : "/std:c++latest" "/clr" ;
