Visual Studio: 2019 C++: 17 Project Info: AddOn migration from ArchiCAD 26 to ArchiCAD 27 - Tech Preview Version

I started learning C++ and for one of our migration projects we use this. Please suggest a resolution that can be implemented.

Hedley-JSON Library Issue 01

I know this is similar to one of the previous issues, but I don't know how this can be solved. Let me know if any further information is needed.

Thanks & Regards

Hey, thanks for filing this. Sorry it took so long for me to get around to looking at it…

We have a CI build for VS 2019 and the fallthrough test doesn't complain. Are you still able to reproduce this problem? If so would it be possible to provide the compiler flags, and a complete version number (just run cl.exe without any arguments, it should print the version)?
