  • .NET: Update Workflow Input/Output Redesign (#881) 
    * feat: Make Executor id field mandatory

When checkpointing is involved, it is critical to keep executor ids consistent between runs, even when recreating a new object tree for the workflow.

The default id-setting mechanism generated a guid for part of the id, making it not work when restoring from a checkpoint.

This change prevents this situation from arising.

* feat: Enable running untyped Workflows

With the change to enable delay-instantiation of executors and support for async Executor factory methods, we must instantiate the starting executor to know what are the valid input types for the workflow.

To avoid forcing instantiation every time, and to better support workflows with multiple input types, we enable support for build and interacting with the base Workflow type without type annotations, and remove the requirement to know a valid input type when initiating a run.

* feat: Support Output from any executor and multiple outputs.

  • .NET: Add AgentWorkflowBuilder group chat (#861) 
    * Add AgentWorkflowBuilder group chat

And fix a variety of issues along the way:
- Use DateTime{Offset}.UtcNow rather than Now
- AIAgentHostExecutor shouldn't be publishing empty messages
- Sequential workflows should be flowing all history and not just the output from the previous agent as the input into the next agent
- Renamed some of the new agent workflow methods... still not super happy with the shape, though
- Simplified handoffs builder, e.g. using a hashset with a custom comparer instead of a dictionary
- Improved multi-service use by trying to change assistant->user role for messages created by other agents
- Changed MessageMerger to rely on M.E.AI's coalescing more and to avoid empty contents / text
- Ensured that messages from ChatClientAgent include MessageId and CreatedAt timestamps
- Avoided including instructions for agents in a handoff workflow that don't have any handoffs
- Removed the unnecessary end function in handoffs
- Improved naming of executors to include agent name for debuggability
- Use "N" formatting with Guid.ToString everywhere, to avoid the unnecessary extra dash character which is also not valid in various places (like function tool names)
- Replace `params T[]` with `params IEnumerable<T>` to make public APIs more flexible in what they consume

* Address feedback

- Fix unintentional provider change in sample

  • fix: Fix Checkpoint Restore when Rehydrating Run (#642) 
    When checkpointing we did not persist the set of instantiated executors. This means, in turn, when we restore from a checkpoint when using Resume(Stream) rather than restoring a checkpoint in the context of an already existing (Streaming)Run, the executors never got reinstantiated and there were no executors to notify that a state should be loaded.

The fix is to ensure we persist the list and reinstantiate the executors on rehydration.

* refactor: Simplify Disposal pattern in Executor

* refactor: Break EdgeRunner file into per-type files

* refactor: Use Throw.IfNull()

* refactor: Remove AddLoop()

Per https://github.com/microsoft/agent-framework/pull/272#discussion_r2241739079 we decided this was not very useful.

  • .NET: fix: FanIn Edge does not work (#541) 
    * fix: FanIn Edge does not work

We were not creating the state for FanIn edge in EdgeMap correctly, leading to crashes. After fixing that, it turns out the logic in FanInEdgeRunner was only forwarding the last message, not all of them.

* fix: Remove duplicate code and fix typo

  • fix: ChatMessage Aggregation in AIAgentHostExecutor (#530) 
    The previous fix for the aggregation in AIAgentHostExecutor has a bug wherein we only include the first update from a ChatMessage in the outgoing "collected" message.

The fix is to ensure we put the collected updates into the message before sending it out.
