IsInitiating
The IsInitiating property specifies whether this operation can be the initial operation in a session.
IsTerminating
The IsTerminating property specifies whether WCF attempts to terminate the current session after the operation completes.
ProtectionLevel
The ProtectionLevel property specifies the message-level security that an operation requires at run time.
