I have a StatefulService with a method. The first argument of the method accepts an interface type that corresponds to one of my Actors. The Actor calls the service method using ServiceProxy, passing this in as the first argument. This compiles file. The signatures match.
When running however, I get an error about an unexpected type of IMyActorType not being known to the DataContractSerializer. I know what this message means. Does ServiceProxy not handle ActorReferences? I know ActorProxy works. I can pass one Actor to another Actor using ActorProxy.
Or is this maybe some problem in my configuration of the StatefulService? Something with my ServiceReplicaListener setup?
I have worked around this issue for now by changing the method signatures of my StatefulService methods to ActorReference. That serializes fine, and I can unpack it on the other side. I would much rather have the proper typing, however.
Service Proxy does not handle the Actor references like Actor Proxy does. Services stack is independent of the actor and does not have knowledge of the actor references. Instead of passing the actor interface, you can pass the actor reference (https://msdn.microsoft.com/en-us/library/azure/microsoft.servicefabric.actors.actorreference.get.aspx) and then bind (https://msdn.microsoft.com/en-us/library/azure/microsoft.servicefabric.actors.actorreference.bind.aspx) the actor reference to the actor interface type on the receiving side. You can cast the output of the binding method to the actor interface.
