Using ngrok for ASP.NET

If you try to just use ngrok like this

ngrok http 1316

You’re likely going to run into an issue when you browse to the website via the ngrok supplied URL that there are invalid host headers. This is because the local server is expecting headers for localhost and instead it is getting them for something like https://3fe1-198-53-125-218.ngrok.io. This can be solved by running with

ngrok http 1316 -host-header="localhost:1316"
