Step 3: Multi-Turn Conversations

Use a session to maintain conversation context so the agent remembers what was said earlier.

Use AgentSession to maintain context across multiple calls:

using System;
using Azure.AI.OpenAI;
using Azure.Identity;
using Microsoft.Agents.AI;

var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")
    ?? throw new InvalidOperationException("Set AZURE_OPENAI_ENDPOINT");
var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME") ?? "gpt-4o-mini";

AIAgent agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential())
    .GetChatClient(deploymentName)
    .AsAIAgent(instructions: "You are a friendly assistant. Keep your answers brief.", name: "ConversationAgent");

// Create a session to maintain conversation history
AgentSession session = await agent.CreateSessionAsync();

// First turn
Console.WriteLine(await agent.RunAsync("My name is Alice and I love hiking.", session));

// Second turn — the agent remembers the user's name and hobby
Console.WriteLine(await agent.RunAsync("What do you remember about me?", session));

Tip

See here for a full runnable sample application.

Use AgentSession to maintain context across multiple calls:

credential = AzureCliCredential()
client = AzureOpenAIResponsesClient(
    project_endpoint=os.environ["AZURE_AI_PROJECT_ENDPOINT"],
    deployment_name=os.environ["AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME"],
    credential=credential,
)

agent = client.as_agent(
    name="ConversationAgent",
    instructions="You are a friendly assistant. Keep your answers brief.",
)

# Create a session to maintain conversation history
session = agent.create_session()

# First turn
result = await agent.run("My name is Alice and I love hiking.", session=session)
print(f"Agent: {result}\n")

# Second turn — the agent should remember the user's name and hobby
result = await agent.run("What do you remember about me?", session=session)
print(f"Agent: {result}")

• Multi-turn conversations — advanced conversation patterns
• Middleware — intercept and modify agent interactions
