1.5.45 July 7th, 2025

Akka.NET v1.5.45 is a minor patch containing bug fixes for Core Akka and Akka.Cluster.Sharding plugin.

• Core: Code modernization, use deconstructor for variable swapping
• Sharding: Fix unclean ShardingConsumerControllerImpl shutdown
• Core: Convert Failure to Exception for Ask<object>
• Core: Fix Settings.InjectTopLevelFallback race condition
• Sharding: Make remembered entities honor supervision strategy decisions

Supervision Strategy For Sharding Remembered Entities

• We've added a SupervisorStrategy property to ClusterShardingSettings. You can use any type of SupervisionStrategy, but it is recommended that you inherit ShardSupervisionStrategy if you're making your own custom supervision strategy.
• Remembered shard entities will now honor SupervisionStrategy decisions and stops remembered entities if the SupervisionStrategy.Decider returned a Directive.Stop or if there is a maximum restart retry limitation.

New Akka.Analyzer Rules

We've added three new Akka.Analyzer rules, AK2003, AK2004, and AK2005. All of them addresses the same Akka anti-pattern where a void async delegate is being passed into the ReceiveActor.Receive<T>() (AK2003), IDslActor.Receive<T>() (AK2004), and ReceivePersistentActor.Command<T>() (AK2005) message handlers.

Here are the documentation for each new rules:

• AK2003 documentation
• AK2004 documentation
• AK2005 documentation
