Microsoft Intellisense not working with setuptools develop #1209

It seems not to find the symbols when I "python setup.py develop" on my environment. This occurs with the builtin intellisense engine. Jedi seems to work ok.

Expected behaviour

When I hover on a symbol, it shows the description.

Actual behaviour

It shows "Code analysis is in progress..." forever.

Steps to reproduce:

1. Create a new conda environment with python and setuptools, and activate
2. Write a hello world program in a file main.py
3. Write a setup.py with this contents:
   from setuptools import setup
   setup(name='test',
   version='1.0',
   scripts=["main.py"],
   )
4. From terminal, type "python setup.py develop"
