  Visual Studio starts [IIS Express](/iis/extensions/introduction-to-iis-express/iis-express-overview) and runs the app. The address bar shows `localhost:port#` and not something like `example.com`. That's because `localhost` is the standard hostname for the local computer. Localhost only serves web requests from the local computer. When Visual Studio creates a web project, a random port is used for the web server.
