The Your code is supported in dotnet standard. Please check the #6 and download it or you try converting to 'netstandard2.1. You will find that that the interfaces are the problem. Not static methods, only interfaces can't have static methods. Tons more code was changed than just static methods. I dont see it being a problem or a performance issue. This library is only used in ApplicationEngine for the syscalls. Plus ApplicationEngine uses tons of reflection to call syscall

That's why I want to remove the static methods in the interface.
