Environment

• Pythonnet version: 2.4.0 (master branch)
• Python version: 3.7.0 (Anaconda)
• Operating System: Windows 10

Details

• Describe what you were trying to get done.

  I think I've successfully installed the pythonnet. And all the demos work. But when I go through the homepage to verify my installation, there's something wrong. I'm sure it's because there's some problem for my installation or any change happened for pythonnet.

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

This usage is from the block of 'Using Arrays' on http://pythonnet.github.io/

I think for pythonnet, most elemental Python types (string, int, long, etc.) convert automatically to compatible managed equivalents (String, Int32, etc.) and vice-versa. So I've no idea about this.
