title: Visual Studio 2015 IronPython
body: <p>So recently I've thought about trying IronPython. I've got my GUI configured, I got my .py file. I click Start in Visual Studio, and that thing pops up: The environment "Unknown Python 2.7 [...]". I have the environment in Solution Explorer set to the Unknown Python 2.7 and I have no idea how to change it. Installed 2.7, 3.5, IronPyhon 2.7 and refreshed them in Python Environments tab</p>
