I am trying to encrypt a section of the web.config file programmatically, using ConfigurationSection.SectionInformation.ProtectSection(), but every time I get an InvalidOperationException with the message "This operation does not apply at runtime." I have tried several provider names as well as null (in order to get the default provider), but I get the same error every time. Any input would be greatly appreciated.
Thanks
