The dev tunnels service is a feature of Visual Studio 2022 and a command-line tool that enables ad-hoc connections between machines that can't directly connect to each other. A URL is created that enables any device with an internet connection to connect to an ASP.NET Core project while it runs on localhost.

Use cases

Some of the scenarios that dev tunnels enable:

• Test a web app on other devices, like mobile phones and tablets.
• Test an app with external services. For instance, test and debug Power Platform connectors, Azure Communication Services APIs, or Twilio webhooks.
• Make an app temporarily available to others over the internet, for a presentation or to invite others to review your work on a web app or API.
• As an alternative to other port-forwarding solutions.

Installation

Install this app in your GitHub organization to enable the dev tunnels service to check the organization membership of users when they attempt to connect to a tunnel that is configured to restrict access to the organization.
