The DLL isn't a COM object or an assembly.  It is an old school (non .Net) API DLL.  So you cannot add it as a reference like that.  You have to use it like you would any WINAPI type DLL.

e.g. this will define mcAxisDeref()

Code: [Select]

[DllImport("Mach4Core.dll", CallingConvention = CallingConvention.StdCall)]
        [return: MarshalAs(UnmanagedType.I4)]
        public static extern int mcAxisDeref(
                [param: MarshalAs(UnmanagedType.I4)]  int mInst,
                [param: MarshalAs(UnmanagedType.I4)]  int axis);
