How to get ngrok working with IISExpress/Visual Studio 2013
netsh add urlacl url=http://modernie.ngrok.com:##### user=everyone
localhost:#####. Click the path next to "Config" to open the file in an editor.<bindings> configuration. The easiest way is to search for *:#####:localhost, which should bring you to the <bindings> section for your site. Edit them to include the following:<bindings>
<binding protocol="http" bindingInformation="*:#####:modernie.ngrok.com" />
<binding protocol="http" bindingInformation="*:#####:localhost" />
</bindings>
Save the file, making sure to replace "modernie" with your subdomain and ##### with your application's VisualStudio/IISExpress port.
ngrok.exe -authtoken XXXXXXXXXXXXXXXXXXXX -subdomain=modernie #####
Make sure to replace "modernie" with your subdomain and ##### with your application's VisualStudio/IISExpress port.
