The configuration system completely parses configuration files to collect configuration information and throws exceptions when it encounters configuration sections that do not have a corresponding entry in the configSections section.

For those sections not handled by the System.Configuration types, the new wrapper type System.Configuration.IgnoreSection is provided. This is to prevent configuration-file parsing exceptions.

For legacy purposes the System.Configuration.IgnoreSectionHandler is also provided.
