I am trying to make a DLL in C# for use in a couple other languages. I found RGiesecke\'s DllExport but it doesn\'t seem to work. It builds just fine and makes a dll, but
This is a good question and worked for me. Just took a bit more time than it should due to the Python side where I made a mistake. Here is the working code in Python3
import sys
import clr
sys.path.insert(0,'C:\\your_path\\Py2NetComm\\bin\\Debug')
clr.AddReference("Py2NetComm")
import ToolServiceDLL as p2n
ret = p2n.Class1.addUp(2,3)
print("addUp:", ret)
