The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

The auth:AdditionalContext element can be used to communicate any additional context for a token request (RST). This context is provided as a collection of name-value pairs, each of which corresponds to a single auth:ContextItem subelement. The auth:ContextItem element is represented by the ContextItem class. You can access the list of context items through the Items property.

For more information about the element that this class represents, see the WS-Federation specification. You can find links to this specification and other WS-* specifications relevant to WIF in the Windows Identity Foundation SDK topic.
