.NET MAUI (Multi-platform App UI) is a cross-platform framework for making Windows, iOS, Android, and macOS apps. ONNX (Open Neural Network Exchange) is a common file format for machine learning models. Attend this session and learn how to build and train a custom machine-learning model using ML.NET, convert it to ONNX then integrate it into MAUI app. We'll also demonstrate how to integrate small language models into a MAUI app. Build One project, One model, One codebase. One heck of a presentation.
