  • .NET: fix: Add session support for Handoff-hosted Agents (#5280) 
    * fix: Add session support for Handoff-hosted Agents

In order to better support using `Workflows` hosted as `AIAgents` inside of Handoff workflows, we need to make proper use of AgentSession. This causes potential issues around checkpointing and making sure that we properly compute only the new incoming messages for each agent invocation.

* fix: AgentSession checkpointing using AIAgent's Serialize/Deserialize methods

We cannot rely on implicit serialization through `HandoffHostState` because we are missing type information.

* fix: Thread safety issue in `MultiPartyConversation.AllMessages`

* fix: Enable unwrapping of FunctionResultContent when ExternalRequest was wrapped into FunctionCallContent

  • .NET: feat: Implement return-to-previous routing in handoff workflow (#4356) 
    * feat: Implement return-to-previous routing in handoff workflow

- Also obsoletes HandoffsWorkflowBuilder => HandoffWorkflowBuilder (no "s")

* refactor: Remove instance-shared current agent tracking in handoffs

Because the tracker was instance-shared between the start and end executors, it would be shared between all sessions, resulting in incorrect behaviour.

The corect way to do this is to keep the data in a shared executor scope, which is per-session.

* fix: Fix test logic for Handoff to correctly use checkpointing for multiturn

  • .NET: [BREAKING] Workflows API Review Naming Changes (Part 1?) (#4090) 
    * refactor: Normalize Run/RunStreaming with AIAgent

* refactor: Clarify Session vs. Run -level concepts

* Rename RunId to SessionId to better match Run/Session terminology in AIAgent
* [BREAKING]: Will break existing checkpointed sessions in CosmosDb due to field rename

* refactor: Rename and simplify interface around getting typed data out of ExternalRequest/Response

* Also adds hints around using value types in PortableValue

* refactor: Rename AddFanInEdge to AddFanInBarrierEdge

This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.

The goal, in the long run is to support a number of different FanIn scenarios, with naive FanIn (no barrier) by default, similar to FanOut.

* refactor: AsAgent(this Workflow, ...) => AsAIAgent(...)

* misc - part1: SwitchBuilder internal

  • fix: .NET: Concurrency Support for Orchestrations (#1689) 
    Concurrent run support was recently added to workflows, but Orchestrations did not fully update to support it. A few executors were missing Cross-Run Shareable annotations, and the ConcurrentEnd executor needed to be factory-instantiated.

This also ports the fix for #1613 from #1637, to avoid waiting on that PR.
