Assembly: System.ServiceModel (in System.ServiceModel.dll)
|A new InstanceContext object is created prior to and recycled subsequent to each call. If the channel does not create a session this value behaves as if it were .|
|A new InstanceContext object is created for each session.|
|Only one InstanceContext object is used for all incoming calls and is not recycled subsequent to the calls. If a service object does not exist, one is created.|
The System.ServiceModel.InstanceContext manages the association between the channel and the user-defined service objects. Use the enumeration with the ServiceBehaviorAttribute.InstanceContextMode property to specify the lifetime of the InstanceContext object. Windows Communication Foundation (WCF) can create a new InstanceContext object for every call, every session or specify that the InstanceContext object is bound to a single service object. For a working example, see the Instancing.
The value specifies that a single InstanceContext object should be used for the lifetime of the service.
