Introduction

The dotnet/ai-samples repository is the official home for .NET samples that showcase how to effectively use AI in your .NET applications. Whether you are new to AI or looking to deepen your understanding, this repository offers a structured path to learning, starting from foundational concepts and progressing to more advanced topics. It primarily focuses on Microsoft.Extensions.AI and Microsoft.Extensions.AI.Evaluation, providing practical examples for various AI scenarios.

Microsoft.Extensions.AI

Microsoft.Extensions.AI is a set of core .NET libraries developed in collaboration with the .NET ecosystem, including Semantic Kernel. These libraries offer a unified layer of C# abstractions for interacting with diverse AI services, such as small and large language models (SLMs and LLMs) and embeddings. Key benefits include a consistent API, flexibility to use any AI provider, ease of use for developers, and improved componentization.

Microsoft.Extensions.AI.Evaluation

Microsoft.Extensions.AI.Evaluation provides .NET libraries with tools to evaluate the quality and efficacy of LLM responses in intelligent applications. Built upon the core AI abstractions from Microsoft.Extensions.AI, these libraries help ensure the reliability and performance of your AI-powered features.

Getting Started

To begin exploring the AI samples, you should clone the repository to your local machine. Each sample typically includes its own README.md file with specific instructions for setup and execution.

git clone https://github.com/dotnet/ai-samples.git
cd ai-samples

Ensure you have the necessary .NET SDK installed. Individual samples may require API keys for services like OpenAI or Azure OpenAI, which you will need to configure according to their respective documentation.

Examples and Quickstarts

The repository is rich with practical examples, categorized for easy navigation. Each link points directly to the relevant README.md within the GitHub repository for detailed instructions.
