The order of service call

By default the service call can be called without any pre-defined order. Microsoft provide a proprietary feature to support ordered call. This is only meaningful only when session is supported. IsInitiating and IsTerminating are two properties of OperationContract attribute. By default IsInitiating is true, means it can be called first in a session. IsTerminating is false by default, means the session can call other service after this call.
