clearing IISExpress cache

Open CMD prompt & Navigate to IIS express - by typing the following

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

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

1. Check the Assembly.GetExecutingAssembly().Location property(watch, immediatewindow) when you are debugging and you are stopped at some Breakpoint
2. you will see a location like below path

%temp%\Temporary ASP.NET Files\vs...\assembly....\YOUR.dll

3. Check out and delete all folders inside thepath (probably possible after closing IIS express and VS)

%temp%\Temporary ASP.NET Files\

In PowerShell, you need to use the call operator (&) to pass parameters/arguments to an executable.

$appCmd = "C:\Program Files (x86)\IIS Express\appcmd.exe"$result = Invoke-Command -Command { & $appCmd 'list' 'sites' '/text:SITE.NAME' }for ($i = 0; $i -lt $result.length; $i++) {    Invoke-Command -Command { & $appCmd 'delete' 'site'  $result[$i] }}

Variation from a comment on this page :

Set-Alias appcmd "$env:ProgramFiles\IIS Express\appcmd.exe"appcmd list site /text:SITE.NAME | % { appcmd delete site $_ }
