Assembly: System.Configuration (in system.configuration.dll)
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 IgnoreSection is provided. This is to prevent configuration-file parsing exceptions.
For legacy purposes the IgnoreSectionHandler is also provided.
See the configSections element of the Machine.config configuration file for examples of sections that specify IgnoreSection as the handling type.
