I am trying to run any program on visual studio 2013 update 3 and I get the following alert box :
Process with an ID #### is not running . // every tim
Close VS. Navigate to the folder of the solution and delete the hidden .vs folder. Restart VS. Hit F5 and IIS Express should load as normal, allowing you to debug.
If this not working, then:
right click your solution and go to properties
Click left menu Web tag
Click checkbox "Override application root Url"
and run again your project.
