Unity il2cpp build problem (WindowsPrincipal::IsMemberOfGroupId - "This call is not supported by il2cpp")

I get this error when building/running using il2cpp:

"NotSupportedException: C:\Program Files\Unity\Editor\Data\il2cpp\libil2cpp\icalls\mscorlib\System.Security.Principal\WindowsPrincipal.cpp(20) : Unsupported internal call for IL2CPP:WIndowsPrincipal::IsMemberOfGroupId - "This icall is not supported by il2cpp."

Am I doing something wrong here....?

Sorry, forgot to mention, building for Android using SDK version

Using Mono backend works fine.


I got the same error on Do you plan to make IL2CPP work anytime soon?

Hi Guys,

I'll check in with the SDK team in relation to this for you.
