Arduino compiles fine, VM/VS fails with ArduinoJson

I've included ArduinoJson library into a large sketch. When building with VM in Visual Studio, in configuration.hpp I get the compile error: arduino configuration.hpp C++ function call is not allowed in a constant expression for if __has_include(<string>). Same for istream and ostream.

If I compile using Arduino, it compiles with no errors?
Am I missing a setting?
I've attached a minimal sketch that exhibits the same issue.

Thanks

Thanks for the report and the project/library.

Can you attach the full build output with the options shown at the top of the page for this test project?

We just want to be sure we are replicating the same issue as currently this compiles fine with the ATMega2560 from the AVR 1.8.6 board package and your library.

I've included images of the output (which compiles fine) and the Erros list with images of the errors flagged in the source.
Is there a compile error level flag I should change for VM?
Thanks
Abbott

Please attach the complete output as a text file, from the Output > Micro Build Window after completing a build.

Without this it is very difficult to understand the environment in use, but it is good to know there are only intellisense issues and no build problems.

The log and your images will allow us to dig deeper into the Intellisense issues once we can replicate them.

Thanks for the log.

Can you change the build configuration from ARM64 to ARM, then make a small edit to your sketch and save it.

Does this improve the Intellisense error?

Can you try the latest release (24.0510.01) which can be downloaded from the top of the below board:
https://www.visualmicro.com/forums/YaBB.pl?board=VS_ARDUINO_EXT_RELEASES

This should improve some of the Intellisense errors you are seeing.  There will still be some errors which we are working on the best way to resolve (e.g. the "new(size_t) functions).
