clearing IISExpress cache

Question

I am trying to clear up the IISExpress Cache from the powershell. Using this code it complains about the list.

"C:\Program Files (x86)\IIS Express\appcmd.exe" list site /xml | appcmd delete site /in

How can I clear up the sites and the IIS Express cache?

Easy: Just open CMD prompt & Navigate to IIS express - by typing the following

cd "C:\Program Files (x86)\IIS Express\"

//paste & run this 
appcmd.exe list site /xml | appcmd delete site /in

This will delete all the sites, enjoy!

Update for PowerShell Version Thanks to @sibbij

cd "C:\Program Files (x86)\IIS Express\"

run this ./appcmd.exe list site /xml | ./appcmd delete site /in
