To co-relate all the messages sent between two endpoints.
WCF sessions have the following main conceptual features:
* They are explicitly initiated and terminated by the
calling application.
* Messages delivered during a session are processed in
the order in which they are received.
* Sessions correlate a group of messages into a
conversation. The meaning of that correlation is an
abstraction. For instance, one session-based channel may
correlate messages based on a shared network connection
while another session-based channel may correlate messages
based on a shared tag in the message body. The features that
can be derived from the session depend on the nature of the
correlation.
* There is no general data store associated with a WCF
session.
When a service contract specifies that it requires a
session, that contract is specifying that all calls (that
is, the underlying message exchanges that support the calls)
must be part of the same conversation. If a contract
specifies that it allows sessions but does not require one,
clients can connect and either establish a session or not
establish a session. If the session ends and a message is
sent through the same channel an exception is thrown.
Except basichttpbinding, wsHttpBinding and NetTcpBinding
supports session.
