Trying to pass a python callback to a C# DLL. Getting Unresolved reference System I am using Pythonnet 2.5.2 on Python 3.7.6 for Win32.

My imports are:

import clr
from System import Action    #Fail Here - Unresolved reference System !
import wx
import wx.lib.filebrowsebutton as filebrowse
import os
import serial
import threading
import time
import configparser

I have tried No module named 'System'.

What is the problem? How can I continue?

    Maybe more than one python installed? Problem with environment variables PYTHONPATH or PYTHONHOME? Does `import sys` `print(sys.version)` give the expected Python 3.7.6? – ToolmakerSteve Jan 07 '22 at 02:20
