HTTP Error 500.22 - Internal Server Error

An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

Most likely causes:

  • This application defines configuration in the system.web/httpModules section.

Things you can try:

  • Migrate the configuration to the system.webServer/modules section. You can do so manually or by using AppCmd from the command line - for example, %SystemRoot%\system32\inetsrv\appcmd migrate config "Default Web Site/". Using AppCmd to migrate your application will enable it to work in Integrated mode, and continue to work in Classic mode and on previous versions of IIS.
  • If you are certain that it is OK to ignore this error, it can be disabled by setting system.webServer/validation@validateIntegratedModeConfiguration to false.
  • Alternatively, switch the application to a Classic mode application pool - for example, %SystemRoot%\system32\inetsrv\appcmd set app "Default Web Site/" /applicationPool:"Classic .NET AppPool". Only do this if you are unable to migrate your application.
(Set "Default Web Site" and "Classic .NET AppPool" to your application path and application pool name)
