The .NET 10 AI Stack

Core Components

1. Microsoft.Extensions.AI

The foundation of AI integration in .NET 10, providing:

// Unified AI service abstraction
public interface IChatClient
{
    Task<ChatResponse> GetResponseAsync(
        string message, 
        ChatOptions? options = null);
}

Key Features:

• Multi-provider support (Azure OpenAI, OpenAI, GitHub Models)
• Middleware pipeline for cross-cutting concerns
• Streaming responses for real-time applications
• Function calling and tool execution

2. Microsoft Agent Framework

Build sophisticated multi-agent workflows:

// Define specialized agents
var analystAgent = new ChatAgent(
    "Data Analyst", 
    "Analyze trends and generate insights");

var writerAgent = new ChatAgent(
    "Content Writer", 
    "Create engaging technical content");

// Orchestrate collaboration
var workflow = new AgentWorkflow()
    .AddAgent(analystAgent)
    .AddAgent(writerAgent)
    .Build();

Capabilities:

• Agent orchestration and collaboration
• State management and persistence
• Tool integration and function calling
• Cloud-native deployment patterns

3. Semantic Kernel Integration

Bridge between LLMs and application logic:

// Create kernel with GitHub Models
var kernel = new KernelBuilder()
    .WithGitHubModelsChatCompletion("gpt-4")
    .WithPluginsFromType<CalculatorPlugin>()
    .Build();

// Use natural language to call functions
var result = await kernel.InvokeAsync(
    "Calculate the compound interest for $10,000 at 5% for 10 years");

Step-by-Step Implementation Guide

Step 1: Setting Up Your Project

Basic Project Structure

dotnet new console -n AIIntegrationDemo
cd AIIntegrationDemo

Add Required NuGet Packages

dotnet add package Microsoft.Extensions.AI
dotnet add package Microsoft.SemanticKernel
dotnet add package Microsoft.Extensions.Configuration.UserSecrets

Step 2: Configuring AI Services

Using GitHub Models (Free Tier)

// Program.cs
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.AI;

var builder = WebApplication.CreateBuilder(args);

// Add GitHub Models configuration
builder.Services.AddGitHubModelsChatClient(
    builder.Configuration["GitHub:Token"],
    "gpt-4"
);

// Add AI chat service
builder.Services.AddChatClient();

var app = builder.Build();

Using Azure OpenAI (Production)

// appsettings.json
{
  "AzureOpenAI": {
    "Endpoint": "https://your-resource.openai.azure.com/",
    "ApiKey": "your-api-key",
    "DeploymentName": "gpt-4"
  }
}

// Program.cs
builder.Services.AddAzureOpenAIChatClient(
    configuration["AzureOpenAI:Endpoint"],
    configuration["AzureOpenAI:ApiKey"],
    configuration["AzureOpenAI:DeploymentName"]
);

Step 3: Building Your First AI Application

Simple Chat Interface

public class ChatService
{
    private readonly IChatClient _chatClient;

    public ChatService(IChatClient chatClient)
    {
        _chatClient = chatClient;
    }

    public async Task<string> GetResponseAsync(string userMessage)
    {
        var response = await _chatClient.GetResponseAsync(userMessage);
        return response.Message.Text;
    }
}

// Usage in API controller
[ApiController]
[Route("api/[controller]")]
public class ChatController : ControllerBase
{
    private readonly ChatService _chatService;

    public ChatController(ChatService chatService)
    {
        _chatService = chatService;
    }

    [HttpPost]
    public async Task<IActionResult> Chat([FromBody] ChatRequest request)
    {
        var response = await _chatService.GetResponseAsync(request.Message);
        return Ok(new { response });
    }
}

Step 4: Advanced Features

Function Calling with AI

// Define available functions
public class WeatherPlugin
{
    [KernelFunction]
    public async Task<string> GetWeatherAsync(string location)
    {
        // Implement weather API call
        return await WeatherService.GetForecast(location);
    }
}

// Register with Semantic Kernel
var kernel = new KernelBuilder()
    .WithPluginsFromType<WeatherPlugin>()
    .Build();

// AI will automatically call the function when needed
var result = await kernel.InvokeAsync(
    "What's the weather in New York tomorrow?");

Multi-Agent Workflows

// Define agent collaboration
public class ResearchAgent
{
    public async Task<ResearchResult> AnalyzeTopicAsync(string topic)
    {
        // Research and gather information
        return await ResearchService.AnalyzeAsync(topic);
    }
}

public class WritingAgent
{
    public async Task<string> WriteArticleAsync(ResearchResult research)
    {
        // Generate content based on research
        return await ContentGenerator.CreateAsync(research);
    }
}

// Orchestrate the workflow
public class BlogGenerationWorkflow
{
    public async Task<string> GenerateBlogPostAsync(string topic)
    {
        var research = await _researchAgent.AnalyzeTopicAsync(topic);
        var article = await _writingAgent.WriteArticleAsync(research);
        return article;
    }
}
