This sample demonstrates how to configure an agent to produce structured output using JSON schema.

  • Deserializing streamed responses into structured types
  • No server-side agent creation or cleanup required

Prerequisites

  • .NET 10 SDK or later
  • Microsoft Foundry service endpoint and deployment configured
  • Azure CLI installed and authenticated (az login)

Set the following environment variables:

$env:AZURE_AI_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project"
$env:AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-5.4-mini"
