No Process Recycling • IIS Express is a user-mode application, not a service Module/Handler Differences • IIS Express ships with URL Rewrite built-in • WebDAV handler is disabled in configuration Extra Environment Variables in Config • %IIS_BIN%, %IIS_USER_HOME%, and %IIS_SITES_HOME% Failed Request Tracing is Enabled • Easier tracing experience

Sites are persistent, similar to IIS Template located at: %ProgramFiles%\IIS Express\config\templates\PersonalWebServer\applicationHost.config

Syntax: iisexpress.exe [/config:config-file] [/site:site-name] [/systray:true|false] [/siteid:site-id] [/userhome:user-home]

Temporary configuration file generated when IIS Express starts Template located at: %ProgramFiles%\IIS Express\AppServer\applicationHost.config

Syntax: iisexpress.exe /path:app-path [/port:port-number] [/clr:clr-version] [/systray:true|false]
