Learn how to build a real AI-powered application in .NET using Ollama, Llama 3, and Microsoft.Extensions.AI — completely locally, without relying on a cloud AI API.
In this tutorial, we'll build a US address parser that takes an unstructured address and converts it into a strongly typed C# object using structured JSON output.
💡 What You’ll Learn
✔️ Configure Ollama and Llama 3 in an ASP.NET Core application
✔️ Using Microsoft.Extensions.AI and IChatClient
✔️ Build an AI-powered service using dependency injection
✔️ Generate structured JSON response from AI
✔️ Convert AI responses directly into strongly typed C# objects
✔️ Design the AI integration using clean abstractions
✔️ Understand important production considerations when using LLMs in .NET
This is a practical introduction to building local AI applications with modern .NET.
