A Message can have zero or more headers that are used as an extension mechanism to pass information in messages that is 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.

Notes to Inheritors

When overridden in a derived class, this method returns a MessageHeaders object for the headers of the message.
