2 API calls that changes that file causes an unhandled exception An unhandled exception has occurred while executing the request.

Exception: System.IO.FileLoadException: Filename: \?...\inetsrv\config\applicationHost.config Error: Cannot commit configuration changes because the file has changed on disk
