Alternative Managed API:

Do you know one? Please contribute it!

    [DllImport("ntdll.dll", EntryPoint = "memcpy")]
    static extern unsafe void CopyMemory(byte* Destination, byte* Source, int Length);

It seems that using the EntryPoint - compiles and runs, yet doesn't always copy the memory. Without the entry point - it does.

Notes:

None.

RtlCopyMemory is (sometimes?) just a C macro expanding to memcpy, not a real exported DLL function.
