* Fix Content serialization in DurableAgentStateUnknownContent (#4719) DurableAgentStateUnknownContent.from_unknown_content() stored raw Content objects without converting them to dicts, causing json.dumps to fail in Azure Durable Functions' entity state serialization. This affected content types not explicitly handled (e.g., mcp_server_tool_call/result). The fix converts Content objects to dicts via to_dict() when storing in DurableAgentStateUnknownContent, and restores them via Content.from_dict() in to_ai_content(). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Add to_json and from_json methods to Content class (#4719) Add to_json() and from_json() methods to the Content class to match the serialization interface provided by SerializationMixin on other model classes. Also fix pre-existing pyright type errors in durabletask's DurableAgentStateUnknownContent.to_ai_content(). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Address PR review: add type guard, remove to_json, add fallback, and tests - Remove Content.to_json() per reviewer request (comment 3) - Add type guard in Content.from_json() for non-dict JSON (comments 1, 4) - Wrap json.JSONDecodeError as ValueError for consistent exception contract - Add try/except fallback in to_ai_content() for invalid Content dicts (comment 5) - Add test_content_to_dict_exclude_none and test_content_to_dict_exclude_fields (comment 2) - Add test_unknown_content_to_ai_content_fallback_on_invalid_type_dict (comment 5) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Apply pre-commit auto-fixes * Address review feedback for #4719: review comment fixes * Remove Content.from_json, move logic to consuming code (#4719) Remove the from_json convenience method from Content class per review feedback. This is the same trivial json.loads + from_dict wrapper as to_json which was already removed. Consumers should call json.loads and Content.from_dict directly. Update tests to use Content.from_dict(json.loads(...)) pattern and remove from_json-specific error handling tests (those errors are already covered by json.loads and Content.from_dict).

History
Get Started with Microsoft Agent Framework Durable Task
Please install this package via pip:
pip install agent-framework-durabletask --pre
Durable Task Integration
The durable task integration lets you host Microsoft Agent Framework agents using the Durable Task framework so they can persist state, replay conversation history, and recover from failures automatically.
Basic Usage Example
from agent_framework import Agent
from agent_framework.azure import AzureOpenAIChatClient
from agent_framework_durabletask import DurableAIAgentWorker
from durabletask.worker import TaskHubGrpcWorker
# Create the worker
worker = TaskHubGrpcWorker(host_address="localhost:4001")
agent_worker = DurableAIAgentWorker(worker)
chat_client = AzureOpenAIChatClient()
my_agent = Agent(client=chat_client, name="assistant")
agent_worker.add_agent(my_agent)
For more details, review the Python README and the samples directory.
