How to listen to the application deletion event in Service Fabric?

Question

I am running a stateless service in Azure Service Fabric in the .NET Framework. I want to perform some clean up activities, and remove some configurations from the registry if all of my applications get deleted from a node in my Service Fabric Cluster. Is there any way that I can do this?

Yes, you can do this by registering notification callbacks. Register for all applications and services by using this code:

var filterDescription = new ServiceNotificationFilterDescription
{
    Name = new Uri("fabric:"),
    MatchNamePrefix = true
};

You interpret a notification with no endpoints as a service deletion.

Have a look at this question too.

Thank you @LoekD. That's what I was looking for. – Kiran Sep 05 '18 at 17:49
How is this different from OnCloseAsync() event?. It is called when the service instance is going to be gracefully shut down. – Blue Clouds Sep 06 '18 at 06:57
The nuance is in 'when all my application gets deleted'; you'd need to know the state of multiple services. – LoekD Sep 06 '18 at 10:14
