I've just published a practical series about building a music recommendation system using ML.NET and ASP.NET Core.

The goal wasn't just to train a recommendation model, but to explain the complete workflow, from understanding how recommendation systems work to evaluating whether the model is actually good enough to be used in a real application.

The series covers:

🎸 How recommendation systems work

📊 How to evaluate a recommendation model

🤖 Training a rock music recommender with ML.NET

📈 Evaluating the recommender's performance

🚀 Exposing the model through an ASP.NET Core Web API
