Looking at VS2013, I’m impressed with it’s speed over VS2012 not to mention that Microsoft appears to be releasing more often and taking into consideration a lot of community feedback. Other than the quickly visible improvements, I noticed that the virtual web server would stop working when debugging was stopped in Visual Studio. To fix this open you ASP.NET project properties and uncheck “Enable Edit and Continue”. Once this is unchecked IIS Express will run after debugging has stopped.
