Evan Mattson c5ed8209df Python: Fix StandardMagenticManager to propagate session to manager agent (#4409)
* Fix #4371: Propagate session to manager agent in StandardMagenticManager

StandardMagenticManager._complete() was calling self._agent.run(messages)
without passing a session. This caused context providers (e.g.
RedisHistoryProvider) configured on the manager agent to silently fail,
as each call created a new ephemeral session with a different session_id.

Changes:
- Create an AgentSession in StandardMagenticManager.__init__()
- Pass session=self._session in _complete() calls to agent.run()
- Persist/restore the session in checkpoint save/restore methods
- Add regression tests for session propagation and checkpoint round-trip

* Add type: ignore[reportPrivateUsage] to private attribute assertions in tests

Address PR review feedback: add # type: ignore[reportPrivateUsage] comments
to _session attribute accesses in the new regression tests, matching the
existing convention used elsewhere in test_magentic.py (e.g., lines 401-406).

The @pytest.mark.asyncio decorator is not needed because pyproject.toml
sets asyncio_mode = "auto".

Fixes #4371

* Address review: use getattr for private _session access in tests (#4371)

Replace direct mgr._session access with getattr(mgr, "_session") to avoid
reportPrivateUsage type-checking warnings without needing type: ignore comments.

* Address PR review: fix session restore guard and improve test robustness (#4371)

- Use 'is not None' instead of truthiness check for session_payload restore
- Use getattr() for private _session attribute access in tests
- Add backward-compatibility test for on_checkpoint_restore with empty state

* Make non-async tests plain def to avoid pytest-asyncio dependency (#4409)

Tests that never await anything don't need to be async. Using plain def
ensures they always run regardless of pytest-asyncio configuration.

Microsoft Agent Framework

Welcome to Microsoft Agent Framework!

Microsoft Azure AI Foundry Discord MS Learn Documentation PyPI NuGet

Welcome to Microsoft's comprehensive multi-language framework for building, orchestrating, and deploying AI agents with support for both .NET and Python implementations. This framework provides everything from simple chat agents to complex multi-agent workflows with graph-based orchestration.

Quickstart

Basic Agent - Python

Create a simple Azure Responses Agent that writes a haiku about the Microsoft Agent Framework

# pip install agent-framework --pre
# Use `az login` to authenticate with Azure CLI
import os
import asyncio
from agent_framework.azure import AzureOpenAIResponsesClient
from azure.identity import AzureCliCredential


async def main():
    # Initialize a chat agent with Azure OpenAI Responses
    # the endpoint, deployment name, and api version can be set via environment variables
    # or they can be passed in directly to the AzureOpenAIResponsesClient constructor
    agent = AzureOpenAIResponsesClient(
        # endpoint=os.environ["AZURE_OPENAI_ENDPOINT"],
        # deployment_name=os.environ["AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME"],
        # api_version=os.environ["AZURE_OPENAI_API_VERSION"],
        # api_key=os.environ["AZURE_OPENAI_API_KEY"],  # Optional if using AzureCliCredential
        credential=AzureCliCredential(), # Optional, if using api_key
    ).as_agent(
        name="HaikuBot",
        instructions="You are an upbeat assistant that writes beautifully.",
    )

    print(await agent.run("Write a haiku about Microsoft Agent Framework."))

if __name__ == "__main__":
    asyncio.run(main())

Basic Agent - .NET

Create a simple Agent, using OpenAI Responses, that writes a haiku about the Microsoft Agent Framework

// dotnet add package Microsoft.Agents.AI.OpenAI --prerelease
using Microsoft.Agents.AI;
using OpenAI;
using OpenAI.Responses;

// Replace the <apikey> with your OpenAI API key.
var agent = new OpenAIClient("<apikey>")
    .GetResponsesClient("gpt-4o-mini")
    .AsAIAgent(name: "HaikuBot", instructions: "You are an upbeat assistant that writes beautifully.");

Console.WriteLine(await agent.RunAsync("Write a haiku about Microsoft Agent Framework."));

Create a simple Agent, using Azure OpenAI Responses with token based auth, that writes a haiku about the Microsoft Agent Framework

// dotnet add package Microsoft.Agents.AI.OpenAI --prerelease
// dotnet add package Azure.Identity
// Use `az login` to authenticate with Azure CLI
using System.ClientModel.Primitives;
using Azure.Identity;
using Microsoft.Agents.AI;
using OpenAI;
using OpenAI.Responses;

// Replace <resource> and gpt-4o-mini with your Azure OpenAI resource name and deployment name.
var agent = new OpenAIClient(
    new BearerTokenPolicy(new AzureCliCredential(), "https://ai.azure.com/.default"),
    new OpenAIClientOptions() { Endpoint = new Uri("https://<resource>.openai.azure.com/openai/v1") })
    .GetResponsesClient("gpt-4o-mini")
    .AsAIAgent(name: "HaikuBot", instructions: "You are an upbeat assistant that writes beautifully.");

Console.WriteLine(await agent.RunAsync("Write a haiku about Microsoft Agent Framework."));

Important Notes

If you use the Microsoft Agent Framework to build applications that operate with third-party servers or agents, you do so at your own risk. We recommend reviewing all data being shared with third-party servers or agents and being cognizant of third-party practices for retention and location of data. It is your responsibility to manage whether your data will flow outside of your organization's Azure compliance and geographic boundaries and any related implications.
