Develop AI apps with .NET

  • Article

This article contains an organized list of the best learning resources for .NET developers who are getting started building AI apps. Resources include popular quickstart articles, reference samples, documentation, and training courses.

Resources for Azure OpenAI Service

Azure OpenAI Service provides REST API access to OpenAI's powerful language models. These models can be easily adapted to your specific task including but not limited to content generation, summarization, image understanding, semantic search, and natural language to code translation. Users can access the service through REST APIs, Azure OpenAI SDK for .NET, or the web-based interface in the Azure OpenAI Studio.

Libraries and samples

Link Description
Azure OpenAI SDK for .NET The GitHub source version of the Azure OpenAI client library for .NET is an adaptation of OpenAI's REST APIs that provides an idiomatic interface and rich integration with the rest of the Azure SDK ecosystem. It can connect to Azure OpenAI resources or to the non-Azure OpenAI inference endpoint, making it a great choice for even non-Azure OpenAI development.
Azure OpenAI SDK Releases Links to all Azure OpenAI SDK library packages, including links for .NET, Java, JavaScript and Go.
Azure.AI.OpenAI NuGet package The NuGet version of the Azure OpenAI client library for .NET.
Get started using GPT-35-Turbo and GPT-4 An article that walks you through creating a chat completion sample.
Completions A collection of 10 samples that demonstrate how to use the Azure OpenAI client library for .NET to chat, stream replies, use your own data, transcribe/translate audio, generate images, etc.
Streaming Chat Completions A deep link to the samples demonstrating streaming completions.
OpenAI with Microsoft Entra ID Role based access control A look at authentication using Microsoft Entra ID.
OpenAI with Managed Identities An article with more complex security scenarios that require Azure role-based access control (Azure RBAC). This document covers how to authenticate to your OpenAI resource using Microsoft Entra ID.
More samples A collection of OpenAI samples written in .NET.

Resources for other Azure AI services

In addition to Azure OpenAI Service, there are many other Azure AI services that help developers and organizations rapidly create intelligent, market-ready, and responsbile applications with out-of-the-box and prebuilt customizable APIs and models. Example applications include natural language processing for conversations, search, monitoring, translation, speech, vision, and decision-making.

Samples

AI app templates

AI app templates provide you with well-maintained, easy to deploy reference implementations that provide a high-quality starting point for your AI apps.

There are two categories of AI app templates, building blocks and end-to-end solutions. Building blocks are smaller-scale samples that focus on specific scenarios and tasks. End-to-end solutions are comprehensive reference samples including documention, source code, and deployment to allow you to take and extend for your own purposes.

To review a list of key templates available for each programming language, see AI app templates. To browse all available templates, see the AI app templates on the Azure Developer CLI gallery.
