NtDll.RtlGetVersion is OK.

public static class NtDll
{
    [SecurityCritical]
    [DllImport(Lib.NTdll, SetLastError = true, CharSet = CharSet.Unicode)]
    [DefaultDllImportSearchPaths(DllImportSearchPath.System32)]
    public static extern int RtlGetVersion(out OSVERSIONINFOEX versionInfo);
}
[StructLayout(LayoutKind.Sequential)]
public struct OSVERSIONINFOEX
{
    public int OSVersionInfoSize;
    public int MajorVersion;
    public int MinorVersion;
    public int BuildNumber;
    public int Revision;
    public int PlatformId;
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 128)]
    public string CSDVersion;
    public ushort ServicePackMajor;
    public ushort ServicePackMinor;
    public short SuiteMask;
    public byte ProductType;
    public byte Reserved;
}

Both those methods (GetVersionEx and RtlGetVersion) are marked as obsolete in lieu of the functions in VersionHelpers.h. You can find the Varana equivalents at PInvoke/Kernel32/VersionHelpers.cs

To use GetVersionEx you have to set the size or use the Default field:

var ver = OSVERSIONINFOEX.Default;
if (!GetVersionEx(ref ver)) ...

Kernel32.OSVERSIONINFOEX.Default make Kernel32.GetVersionEx return true, but it seems that the value is not eq to NtDll.RtlGetVersion.

Kernel32.GetVersionEx

NtDll.RtlGetVersion
