yaoleo34 · 2026-02-27T19:53:28Z

Motivation and Context

Description

This pull request introduces a new multi-agent workflow sample (foundry_multiagent) for Azure AI Foundry using the Microsoft Agent Framework. Both samples are designed for local development and deployment to Microsoft Foundry.

Multi-Agent Workflow Sample (foundry_multiagent):

New multi-agent workflow implementation:
Introduces a new sample in foundry_multiagent that creates and orchestrates two agents (Writer and Reviewer) using the AgentServer SDK

Single-Agent Sample (foundry_single_agent):

Seattle Hotel Agent implementation:
Adds a new sample agent that provides hotel recommendations in Seattle, including a tool function for simulated hotel availability.

Contribution Checklist

The code builds clean without any errors or warnings
The PR follows the Contribution Guidelines
All unit tests pass, and I have added new tests where possible
Is this a breaking change? If yes, add "[BREAKING]" prefix to the title of the PR.

Pull request overview

Adds new Azure AI Foundry “hosted agent” samples (Python + .NET) to support local development and Foundry deployment scenarios, including a single-agent hotel assistant and a multi-agent writer/reviewer workflow.

Changes:

Introduces Python hosted-agent samples: foundry_single_agent (Seattle hotel tool) and foundry_multiagent (writer/reviewer workflow), with Dockerfiles + Foundry agent.yaml manifests.
Introduces .NET hosted-agent samples: single-agent hotel assistant and multi-agent writer/reviewer workflow, with Dockerfiles + agent.yaml + request examples.
Adds end-to-end sample documentation for running locally and deploying via the Foundry VS Code extension.

The python samples are not good, I would advice removing them from this PR and then once the agentserver package has been updated to work with rc2 resubmit them

Python hosted agent samples need further alignment with the azure-ai package conventions. Removing from this PR to ship .NET samples first. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
