You need to set the calling convention. The default convention (stdcall) is not correct, which will cause P/Invoke stack imbalances.
For example, your first call should look like:
[DllImport("Service.dll", CallingConvention=CallingConvention.Cdecl)] static private extern IntPtr CallCreateClass();
By default, C and C++ use cdecl - but marshalling uses stdcall to match the Windows API.
