Just posting this here instead of bumping the thread in archive. I got this problem during IL2CPP build: Code (CSharp): Cannot open include file: 'string.h': No such file or directory Could it be made more obvious that the C++ Workload needs to be installed? Or would it be possible to have it installed implicitly? Without the thread above I wouldn't have had any idea that I'd need to install that. I didn't find anything about it in the documentaiton either.
