Remarks

Dictionaries establish a mapping between commonly appearing text strings, and integers, and provide an effective mechanism for compressing and decompressing XML. Windows Communication Foundation (WCF) uses 2 kinds of dictionaries, static and dynamic.

With static dictionaries, both sides of the communication use a predefined dictionary.

With dynamic dictionaries, the sending side can add new strings and their mappings not already in the static dictionary. Dynamic dictionaries are sent out of band with the message. Dynamic dictionaries use the XmlBinaryWriterSession and XmlBinaryReaderSession classes to transmit messages and mappings.
