If you're getting the following error `unable to resolve 'clr'`:

[![Example Error][0]][0]

It's likely that you don't have a python interpreter *installed* or *configured* for Visual Studio

Per the question [The environment ironpython 2.7-32 appears to be incorrectly configured or missing][1a]

> The Visual Studio Installer does *not* include an IronPython Package option to install

So you need to: 

1. [Download IronPython from Github][1] and install it
2. Then, select the correct [Python environment within your VS project][2].

Steps to reproduce:

1. I created a new project in Visual Studio
2. Selected Python > Desktop > "IronPython Windows Forms Application"

However, as soon as I open the project I encountered several errors which I don't know how to solve. The errors are unresolved import clr an similar.
