A message object is the delivery vehicle for Windows Web Services. A single message object can be used to send or receive sequential messages. Reusing a message object in this way can reduce memory allocations. When you no longer need the message, you must free the memory by calling WsFreeMessage. (For more information on reusing message objects, see WsResetMessage .)

If you are creating a message for use with a particular channel, use the WsCreateMessageForChannel function, which will ensure the correct message version for the channel.
