Can you control when the service instance is recycled?

Yes, we can control when the service instance is recycled using the ReleaseInstanceMode property of the OperationBehavior attribute. You can control the lifespan of your WCF service. You can set the value of ReleaseInstanceMode property as one of the following:

• RealeaseInstanceMode.None: No recycling behavior.
• RealeaseInstanceMode.BeforeCall: Recycle a service object before an operation is called.
• RealeaseInstanceMode.AfterCall: Recycle a service object after an operation is called.
• RealeaseInstanceMode.BeforeAndAfterCall: Recycle a service object both before and after an operation is called.

In this post I explained how to control when the service instance is recycled. I hope it is very helpful for you. Please comments your feedback and quries. Thank You.
