  • .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: [BREAKING] Support Checkpoint Serialization (#735) 
    * feat: Support Checkpoint Serialization

* Implements serialization roundtripping for checkpoints.
* Adds support for JSON serialization
* Adds FileSystem-based checkpoint persistence

* fix: Executor State does not deserialize correctly

The StateManager was not properly handling delay-deserialized values.

* Fix PortableValue handling in StateManager (this makes it delegate to PortableValue the uwnrapping)
* Fix UnitTest to actually test checkpoint serialization
* Additional review comment fixes

  • .NET: BREAKING Update AIAgent.Run to take IEnumerable instead of IReadonlyCollection (#729) 
    * Update AIAgent,Run to take IEnumerable instead of IReadonlyCollection

* Address PR comment.

* Cast to IReadonlyCollection since this is typically all that is required to avoid unecessary allocation.

* Update OrchestratingAgent protected methods as well.
