Hi William,
Create a new WEB SITE by going to New Web Site and selecting this option:
use the defaults and once the site is generated look in the Solution Explorer and you'll see the once of those folders list in the KBA:
Edit the RouterConfig.cs file and make the change according to the KBA article.
This is all new to in VS 2013 so upgrading an older WEB app likely is not going to have those folders and the config files. Possibly just adding them may work but you should ask Microsoft how to.
These are being generated by the default Templates they created for VS 2013, we can't modify them so the KBA is how to alter the behaviour.
