This seems to be related to #506. Please check the develop version where we added parentheses around the min/max calls to fix this MSVC error.

(Note that the develop branch is unreleased and subject to change until version 3.0.0)

For the record I had the same problem in two places.

The problem was not at all the json header code, but other header files defining things that conflict with STD, STL, defaults.

My project has a couple of large dependencies with a lot of header files.
I only have #include "json.hpp" in one place. I just had to add two "#undef xxx" statements just before it. Where "xxx" where the name of the conflicting defines done elsewhere before "json.hpp".
In Visual Studio highlight the problem define and press F12 (the default jump to definition key) so you can see where the problem originated.
