Stop Debugging stops IIS Express hence application stop running in browser in Visual Studio 2015
Note: This was a bug with Visual Studio 2015 Update 2 which is officially mentioned and fixed in Update 3. Read more here . This is not a bug but as a web developer I personally expect when debugging stops browser should keep running through IIS Express instance. Next time, I make change in Visual Studio code then do a build and refresh browser, I’m addicted this way.
