Remarks

A message header contains optional metadata that describe a message encapsulated by the Message class.

A Message can have zero or more headers that are used as an extension mechanism to pass information in messages that are application-specific. You can use Headers to add message headers to a message by calling the Add method.

Windows Communication Foundation (WCF) provides a number of predefined message headers, as shown in the following table.

Header Name	Description
To	Contains the role that the message is targeting.
Action	Provides a description of how the message should be processed.
FaultTo	Contains the address of the node to which faults should be sent.
From	Contains the address of the node that sent the message.
Request	Indicates whether the message is a request.
MessageID	Contains the unique ID of the message.
RelatesTo	Contains the IDs of messages that are related to this message.
ReplyTo	Contains the address of the node to which a reply should be sent for a request.

Constructors
