On Microsoft the API is public for example

// Summary:
// Gets the underlying network System.Net.Sockets.Socket.
// The underlying System.Net.Sockets.Socket.
public Socket Server { get; }

On Mono it is On Mono it is protected Socket Server { get; }

Thus the module is compiled on Windows using VS2005, then the program is 
executed under Mono an error occurs becuase it thinks the Server is public, 
but it is protected,
