Since upgrading to Visual Studio 2013 I’ve noticed a change in behaviour in IIS. It still starts up when you start debugging a web project – same as it always has – but since the upgrade it automatically shuts down when you stop debugging.
As with most IDE behaviour, I was pretty familiar with the old way and so I found it incredibly frustrating whenever this happened. The good news is that there’s a very simple solution: disable Edit and Continue for the project in the Properties dialog.
Hopefully this will save someone else some pain!
