Member name Description
Supported by Silverlight for Windows Phone Input The message is incoming.

This is from the perspective of the server, so an incoming message is sent by a client.

Supported by Silverlight for Windows Phone Output The message is outgoing.

This is from the perspective of the server, so an outgoing message is received by a client.

Remarks

The direction of a message indicates whether the message is coming into an endpoint or going out from an endpoint. Input is incoming to the server and Output is outgoing from the server. For a basic request/response message pattern, a request is incoming to the server and the response is outgoing from the server. On callbacks from the server to client, however, a request is outgoing from the server and a response is incoming to the server.

Use the MessageDescription(String, MessageDirection) constructor to specify the direction of a message.

Retrieve the direction of a message using the Direction property.
