Getting Started with .NET 8 and AI: Quickstart Tutorials

Introduction

With the release of .NET 8, Microsoft has introduced powerful new features and enhancements that make it an excellent choice for developing AI applications. Whether you are a seasoned developer or just starting with AI, .NET 8 provides a robust framework and tools to streamline your development process. In this article, we’ll explore some quickstart tutorials to help you dive into .NET 8 and AI.

Prerequisites

Before diving into the tutorials, ensure you have the following prerequisites installed:

1. .NET 8 SDK: Download and install the .NET 8 SDK from dotnet.microsoft.com.
2. Visual Studio or Visual Studio Code: Choose your preferred IDE. Visual Studio provides a rich integrated environment, while Visual Studio Code offers lightweight flexibility.

Tutorial 1: Setting Up Your .NET 8 Environment

1. Create a New Project:

• Open your IDE (Visual Studio or Visual Studio Code).
• Create a new .NET 8 project:

       dotnet new console -n MyAIProject

• This command creates a new console application named MyAIProject.

2. Install Required Packages:

• Navigate to your project directory and install the required AI packages:

      dotnet add package Microsoft.ML

• This package includes the necessary libraries for machine learning in .NET.

Tutorial 2: Building Your First AI Model

1. Import Necessary Libraries:

• Open your Program.cs file.
• Add the following using the statement at the top:

 using Microsoft.ML;

2. Define Your Model:

• Add code to define and train your model. For example:

// Define your data model

public class SampleData

{

    public float Feature1 { get; set; }

    public float Feature2 { get; set; }

    public float Label { get; set; }

}

// Load data

var data = new List<SampleData>

{

    new SampleData { Feature1 = 0.2f, Feature2 = 0.5f, Label = 1.0f },

    new SampleData { Feature1 = 0.4f, Feature2 = 0.7f, Label = 1.0f },

    // Add more data…

};

// Create a learning pipeline

var pipeline = mlContext.Transforms.Concatenate(“Features”, “Feature1”, “Feature2”)

                          .Append(mlContext.BinaryClassification.Trainers.LbfgsLogisticRegression());

// Train your model

var model = pipeline.Fit(mlContext.Data.LoadFromEnumerable(data));

3. Evaluate and Use Your Model:

• Add code to evaluate and use your trained model for predictions.

Tutorial 3: Integrating AI into Your Application

1. Build a Prediction Engine:

• Modify your Program.cs to include a prediction engine:

// Create a prediction engine

var predictionEngine = mlContext.Model.CreatePredictionEngine<SampleData, Prediction>(model);

// Make predictions

var prediction = predictionEngine.Predict(new SampleData { Feature1 = 0.1f, Feature2 = 0.3f });

Console.WriteLine($”Prediction: {prediction.PredictedLabel}”);

2. Run Your Application:

• Build and run your application to see the AI model in action:

dotnet run
