How to get ngrok working with IISExpress/Visual Studio 2013

ngrok-with-IISExpress.md

1. Decide on a subdomain to use with ngrok. This makes the whole process easier.
2. Open up a Command Prompt in Administrator mode and run the following command to register the URL with HTTP.sys replacing "modernie" with your subdomain and ##### with your VisualStudio/IISExpress application's port.

netsh add urlacl url=http://modernie.ngrok.com:##### user=everyone

3. Edit your applicationhost.config. The easiest way to is start up the site and right-click the IISExpress icon in the System Tray. Click "Show All Applications" and select your website running at localhost:#####. Click the path next to "Config" to open the file in an editor.
4. Search for you site's <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.

5. Restart your site.
6. Run ngrok with the subdomain settings from a Command Prompt running in Administrator mode. This can be done with the following command:

ngrok.exe -authtoken XXXXXXXXXXXXXXXXXXXX -subdomain=modernie #####

Make sure to replace "modernie" with your subdomain and ##### with your application's VisualStudio/IISExpress port.

@ProNotion and everyone, I built a Visual Studio extension to make this easier. Please let me know what you think:

@moranm6 did you ever solve this? I also need this solution so I can convince "management" to pay for this tool.

@dprothero It works a treat - thanks so much for taking the time and for sharing. I'm still curious - why I can't get it work from the command line myself anymore but thanks for a great extension!

Tried dprothero's command above, as well as the extension. Tried netsh and editing applicationhost.config. In every case, what I get when I try to visit the ngrok url is:

a) in my ngrok client, I see the request come in - so it is getting to my machine
b) the request takes quite a while - ballpark 2 minutes?
c) eventually comes back 502

Anyone else running into this with VS2017?

@tscbp The latest version of ngrok resolves the issue see inconshreveable/ngrok#448 and my answer at the SO article you mentioned: VS 2017 IIExpress ngrok SO Article
