🌍 AI Travel Agent with Microsoft Agent Framework (.NET)

📋 Scenario Overview

This example demonstrates how to build an intelligent travel planning agent using the Microsoft Agent Framework for .NET. The agent can automatically generate personalized day-trip itineraries for random destinations around the world.

Key Capabilities:

• 🎲 Random Destination Selection: Uses a custom tool to pick vacation spots
• 🗺️ Intelligent Trip Planning: Creates detailed day-by-day itineraries
• 🔄 Real-time Streaming: Supports both immediate and streaming responses
• 🛠️ Custom Tool Integration: Demonstrates how to extend agent capabilities

🔧 Technical Architecture

Core Technologies

• Microsoft Agent Framework: Latest .NET implementation for AI agent development
• Azure OpenAI (Responses API): Uses the Azure OpenAI Responses API for model inference
• Azure Identity: Secure sign-in via AzureCliCredential (az login)
• Secure Configuration: Environment-based endpoint management

Key Components

1. AIAgent: The main agent orchestrator that handles conversation flow
2. Custom Tools: GetRandomDestination() function available to the agent
3. Responses Client: Azure OpenAI Responses-based conversation interface
4. Streaming Support: Real-time response generation capabilities
