If you see a different icon, right-click your site in VS and choose Use IIS Express. If you don’t
see the icon in the tray, click the arrow near the other icons in the Windows tray and click the
Customize option. Then set IIS Express System Tray to Show Icon and Notifications. The icon
belongs to the built-in web server called IIS Express. This web server has been started by VS automatically
to serve the request for your page. You learn more about how the web server processes
your page later in this chapter.
