If you are running Windows Server 2012 with IIS8 and you got this error HTTP Error 500.19 – Internal Server Error. If you web.config file contains “handler” or “modules” tag. In order to fix this, launch cmd or powershell and execute these 2 commands inside of C:\Windows\System32\InetSrv

{

throw new InvalidOperationException("Expression must be a method call");
