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.

Silverlight 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.

The following code example shows a basic client using the channel factory to send a message and read the action header from the reply.
