ML.NET

Microsoft's free toolkit for adding machine learning to apps written in .NET.

New this week

What it does

ML.NET is a machine learning framework for .NET, Microsoft's family of programming languages such as C#. It lets developers build, train and use their own AI models inside their apps.

Its makers say you don't need prior machine learning experience. It covers tasks like sorting things into groups, forecasting and spotting unusual data, and can also use models made with TensorFlow and ONNX.

It runs on Windows, Linux and macOS.
