How to run P / Invoke in kernel32.dll on WinRT 8.1

Question

I am trying to use my own API method ( GetNativeSystemInfo), which is marked as supported for both phone and desktop applications in Windows 8.1. In the documentation, she is listed as living in kernel32.dll. Big! So, my first P / Invoke attempt looked like this:

[DllImport("kernel32.dll", CharSet = CharSet.Unicode, ExactSpelling = false, PreserveSig = true)]
private static extern void GetNativeSystemInfo(ref SYSTEM_INFO lpSysInfo);

Unfortunately, this does not work on real devices - kernel32 was not found! As it happens, there is kernelBase.dll, and therefore, my second attempt:

[DllImport("kernelBase.dll", CharSet = CharSet.Unicode, ExactSpelling = false, PreserveSig = true)]
private static extern void GetNativeSystemInfo(ref SYSTEM_INFO lpSysInfo);

While this works fine on my phone, this leads to the completion of the certification of the application; the method name and "kernelBase.dll" do not seem to be white.

Is this WACK surveillance or a bug that makes this API unusable in Store apps? My goal is to get information about the running processor (architecture, type, etc.), and I would prefer not to go to C ++ for something so simple. If this API is not practical, is there any other way to get this information?

For Windows Phone and versions of the Windows Store, you'll need different pinvoke signatures. For the phone link GetNativeSystemInfo from api-ms-win-core-sysinfo-l1-2-0.dll

#if WINDOWS_PHONE_APP
     [DllImport("api-ms-win-core-sysinfo-l1-2-0.dll", CharSet = CharSet.Unicode, ExactSpelling = false, PreserveSig = true)]
     private static extern void GetNativeSystemInfo(ref SYSTEM_INFO lpSysInfo);
#else
     [DllImport("kernel32.dll", CharSet = CharSet.Unicode, ExactSpelling = false, PreserveSig = true)]
     private static extern void GetNativeSystemInfo(ref SYSTEM_INFO lpSysInfo);
#endif
