In order to asses your issue, we need the following information:

• What is the issue you have?

• Please describe the steps to reproduce the issue. Can you provide a small but working code example?

• What is the expected behavior?

• And what is the actual behavior instead?

• Which compiler and operating system are you using? Is it a supported compiler?

• Did you use a released version of the library or the version from the develop branch?

• If you experience a compilation error: can you compile and run the unit tests?

Thanks for your reply.
my system is windows 10 (1930) , Visual Studio 2019 (16.3.9).
I use cmake-gui 3.15.5 to generate the vs project .
then i choise genetator Visual Studio 15 2017 and use default native compilers .
configure and generate by all default settings .
after open nlohmann_json.sln and run ALL_BUILD target ,
test-class_parser.vcxproj test-utd.vcxproj test-unicode.vcxproj can not be passed.

That is strange as we use MSVC 2019 in our CI without problems.
