Within some cases you would like to kill local asp.Net Development server process before starting debug modus from your website.
By adding the following command into the startoption section in web-project settings you can force stopping the local ASP.Net server on each start.
TASKKILL /IM WebDev.WebServer.exe
I need this for testing some cache logic :D and it works great. Saves lot of time in comparison with rightclicking the Server symbol in tray and hitting exit :D
