Jupyter notebooks, <code>pip install</code>, Conda environments — none of it maps to how most of us actually ship software.</p> <p>If you're a .NET developer who wants to build real AI-powered features — not toy demos — into your applications, I wrote a free ebook for exactly that: <strong><a href="https://leanpub.com/promptengineeringfornetdevelopers" rel="noopener noreferrer">Prompt Engineering for .NET Developers</a></strong>.</p> <h2> Why I wrote this </h2> <p>Every prompt engineering tutorial I found was Python-first. Meanwhile, <code>Microsoft.Extensions.AI</code> gives .NET developers a clean, unified abstraction over LLM providers — LM Studio, OpenAI, Azure AI Foundry — using the exact same <code>IChatClient</code> interface. There was no practical, runnable guide to prompt engineering that met C# developers where they already live.</p> <p>So I built one.</p> <h2> What's inside </h2> <p>Seven focused chapters, each ending in a <strong>runnable C# project</strong>:</p> <ol> <li> <strong>The .NET Developer's AI Landscape</strong> — the cost spectrum and Microsoft's AI stack</li> <li> <strong>Setting Up Your AI Dev Environment</strong> — LM Studio, OpenAI, Azure AI Foundry, all via the same interface</li> <li> <strong>How LLMs Work</strong> — just enough theory to write better prompts, no transformer lecture</li> <li> <strong>Anatomy of a Great Prompt</strong> — you'll build a fluent <code>PromptBuilder</code> class</li> <li> <strong>Core Prompting Techniques</strong> — zero-shot, few-shot, chain-of-thought, and how to handle sycophancy (the silent failure mode where the model just tells you what you want to hear)</li> <li> <strong>Structured Outputs and Advanced Patterns</strong> — defensive JSON parsing, streaming, resilience</li> <li> <strong>Prompt Patterns for Real Developer Workflows</strong> — you'll carry <code>PromptBuilder</code> into <code>DevToolkit</code>, a console app that does AI-powered code review, test generation, commit messages, and docs</li> </ol> <p>No Jupyter. No Python. Just <code>dotnet new console</code> and code that runs.</p> <h2> Try it in 5 minutes </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>git clone https://github.com/taswar/PromptEngineeringForDotNetDevelopers <span class="nb">cd </span>PromptEngineeringForDotNetDevelopers/chapter-04/src/PromptBuilder dotnet run </code></pre> </div> <p>That's the PromptBuilder fluent class from Chapter 4, running against a local model — zero API cost.</p> <p>Get it<br> 📥 <a href="https://leanpub.com/promptengineeringfornetdevelopers" rel="noopener noreferrer">Download free on Leanpub</a> (pay-what-you-want, including $0)<br> ⭐ <a href="https://github.com/taswar/PromptEngineeringForDotNetDevelopers" rel="noopener noreferrer">Star it on GitHub</a> if it's useful — it's the best free way to help other .NET devs find it<br> 🐛 Found a typo or have a suggestion?
