No Python, No PhD: Train Real ML Models in C# with ML.NET (Regression, Classification, Clustering)

Mattrx ran its predictive features on a Python scikit-learn microservice for two years. We replaced it with ML.NET running in-process inside the existing .NET 9 app — and trained real regression, classification, and clustering models in C# with no separate service, no second language in production, and no implementing gradient descent by hand.
