Best way to clean up resources in StatefulService

Question

I have a services activated in shared process model. My service base class extends StatefulService class like this:

public class MyStatefulService : StatefulService, IDisposable
{
   public StatefulServiceBase(
     StatefulServiceContext serviceContext,
     IReliableStateManagerReplica2 reliableStateManagerReplica)
   : base(serviceContext, reliableStateManagerReplica)

   public void Dispose()
   {
       // my cleanup code
   }
}

I noticed that Service Fabric never calls Dispose() method in my class. Is there a different approach for disposing/cleaning up resources?

Answer 1

There is no support for IDisposable, there is a ticket for it but it is still open.

You can override the StatefulServiceBase.OnCloseAsync() method and cleanup there or act on the cancellation request of the cancellation token passed to RunAsync().
