Property Value


An IInstanceProvider object that controls the creation and destruction of service objects associated with an InstanceContext object.


Implement the IInstanceProvider interface and assign the implementation to the InstanceProvider property to control instances of the service type using a constructor other than the parameterless constructor, for example, to implement a custom instancing mode such as instance pooling.

Typically the GetInstance method is invoked once, when the InstanceContext object is first created. The ReleaseInstance method is also invoked once, when the InstanceContext object is closed.

A service can also be configured to release an instance before the InstanceContext object is closed. This can be configured by using the ReleaseInstanceMode property or by calling the ReleaseServiceInstance method. If this is done, the InstanceContext object calls the ReleaseInstance method. If a new message arrives after the instance has been released, a new instance is created using the GetInstance method.
