Prompt — Azure OpenAI Library

Welcome to the documentation for Prompt, a lightweight .NET 8 library for Azure OpenAI chat completions.

Overview

Prompt provides a clean, minimal API for integrating Azure OpenAI into .NET applications. It handles the boilerplate — connection pooling, retry policies, environment configuration — so you can focus on building.

Key Features

  • Single-call prompts — Main.GetResponseAsync() for quick one-shot interactions
  • Multi-turn conversations — Conversation maintains full message history across turns
  • Template engine — PromptTemplate with {{variable}} placeholders and composition
  • Prompt chaining — PromptChain pipes outputs between steps for multi-step reasoning
  • Model presets — PromptOptions with factory methods for code generation, creative writing, summarization, and data extraction
  • Automatic retries — Exponential backoff for 429 rate-limit and 503 service errors
  • Serialization — Save/load conversations, templates, and chains as JSON
  • Thread-safe — Singleton client with connection pooling, safe for concurrent use

Quick Start

dotnet add package prompt-llm-aoi

using Prompt;

// One-shot prompt
string? response = await Main.GetResponseAsync("Explain quantum computing.");
Console.WriteLine(response);
