Building a Rock Music Recommender with ML.NET: From Training to Model Evaluation

Rafael Arantes — Fri, 24 Jul 2026 23:27:14 +0000

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
