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.
