- Azure.AI.AgentServer.AgentFramework -> 1.0.0-beta.11
- Microsoft.Agents.AI.OpenAI -> 1.0.0-rc4
- Microsoft.Agents.AI/AzureAI/Workflows -> 1.0.0-rc4

file to remove all references.

* Fix AgentWithHostedMCP: downgrade Azure.AI.OpenAI to 2.8.0-beta.1 for rc4 compatibility

Azure.AI.OpenAI 2.9.0-beta.1 has breaking changes (GetResponsesClient no
longer accepts deployment name, ResponsesClient.Model removed) that are
incompatible with Microsoft.Agents.AI.OpenAI rc4. Pin to 2.8.0-beta.1 and
use GetResponsesClient(deploymentName).AsAIAgent() pattern.

What this sample demonstrates

This sample demonstrates the use of AI agents as executors within a workflow.

This workflow uses three translation agents:

  1. French Agent - translates input text to French
  2. Spanish Agent - translates French text to Spanish
  3. English Agent - translates Spanish text back to English

The agents are connected sequentially, creating a translation chain that demonstrates how AI-powered components can be seamlessly integrated into workflow pipelines.

For common prerequisites and setup instructions, see the Hosted Agent Samples README.

Prerequisites

Before you begin, ensure you have the following prerequisites:

  • .NET 10 SDK or later
  • Azure OpenAI service endpoint and deployment configured
  • Azure CLI installed and authenticated (for Azure credential authentication)

Note: This demo uses DefaultAzureCredential for authentication, which probes multiple sources automatically. For local development, make sure you're logged in with az login and have access to the Azure OpenAI resource. For more information, see the Azure CLI documentation.

Set the following environment variables:

$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/" # Replace with your Azure OpenAI resource endpoint
$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"  # Optional, defaults to gpt-4o-mini
