Debugging doesn’t have to stop at your local machine. With Dev Tunnels in Visual Studio, you can securely expose your locally running apps to other devices—or even other people—in seconds. Want to test a mobile app on your phone while it’s running under the debugger? Need to share your in‑progress API with a teammate and hit breakpoints as they try it? Dev Tunnels makes this seamless.

In this session, we’ll explore what Dev Tunnels are, how they work, and why they’re becoming an essential tool for modern app development. You’ll learn the different tunnel modes, security options, and workflow integrations inside Visual Studio. We’ll wrap up with a real-world walkthrough: using Dev Tunnels to test a Power Platform custom connector against a locally running API.

You'll leave with the skills to debug across devices, collaborate more easily, and remove many of the traditional “it only works on my machine” barriers.
