Dev Tunnels gives developers a way to make ad-hoc connections between devices that otherwise would not be able to communicate. Have you ever wanted to bring up an application on your phone that is being debugged in Visual Studio? Or wanted to give someone a link to the app you are debugging and cause break points to be hit? Dev Tunnels facilitates this and more.

In this intro to Dev Tunnels, we'll see how to use it, the options that it provides and a quick demo of a real-world scenario - testing a power platform custom connector.
