What is this?
ML.NET is Microsoft’s machine-learning framework for .NET — train and run models in C# with MLContext.
Why should you care?
AIPredict stays in the .NET stack: same language as ASP.NET Core APIs.
See it live — copy this example
Use a .NET console or Web API project with Microsoft.ML. Run dotnet run after pasting.
using Microsoft.ML;
var ml = new MLContext(seed: 1);
Console.WriteLine($"ML.NET ready: {ml.GetType().Name}");What happened?
- Create one MLContext (optionally seeded).
- Most AIPredict services hold it as a singleton for training tools and load models for inference.
Practice next
- dotnet new console -n AIPredict.Lab
- dotnet add package Microsoft.ML
- New MLContext and run.
- Print ml.BinaryClassification trainer list length.
- Try seed: null vs 1.
Remember
ML.NET = ML in C#. MLContext is the entry point. Same stack as ASP.NET.
AIPredict.Lab first MLContext
Devs confirm Microsoft.ML installs.
Outcome: Ready for IDataView lessons.
