Public Enum MessageDirection
The message is incoming.
The message is outgoing.
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.
