Rails woes on Windows 10

The Rails community isn't strong on support for Windows based machines.

The github repository RubyOnWindowsWoes contains the source and issues found.

This note is to remind me how I eventually solve the problems!

ConfigurationManager does not exist in the current context

This was plaguing me for some time.

Part of the solution is the
#include System.Config

The bit I kept missing was to include the System.Configuration reference to the project.

Sigh.
