I am using a Web application with a web.config file larger than 250KB on IIS 10. In IIS 8.5 and below the registry key HKLM\SOFTWARE\Wow6432Node\Microsoft\InetStp\Configuration\MaxWebConfigFileSizeInKB (REG_DWORD) could be set to allow web.configs to be larger than 250KB. However it seems that this registry key is not read by IIS 10 any longer.
Does anyone know if this key should still work on IIS 10 or how to use config files larger than 250KB in combination with IIS 10?
