"You're not a Software Engineer" - Nick Chapsas

Nick Chapsas opened his NDC Oslo keynote with a question: who are you? We sat outside the venue straight after and I asked him what happens when the answer stops being "software engineer". He thinks the job most of us trained for is gone, and not because AI writes better code. Because doing it by hand stopped being worth the time. So we spent an hour on what is left that is actually yours. Why everything built with an agent is starting to look the same, and what that says about identity. How Dometrain hires with no interviews, no job titles and no meetings. And how they put AI inside the product instead of just using it to build the product. One take, outside, no script. The seagulls are part of it and so is the audio. I'm also a Dometrain author, which is how Nick and I know each other.

The First Rule of AI Solutions Architecture

Before you build an AI agent, ask whether your problem actually needs one. In Season 0, Episode 0 of my Enterprise AI Architecture series, I walk through the difference between a simple process, a workflow, a document-based chatbot, and an AI agent. Using practical examples, we explore when conventional software is enough and when a system may benefit from dynamically choosing its next steps. We start with filtering numbers and importing CSV files into a database, then move into invoice routing and a more open-ended request: finding invoice errors and deciding how to address them. Good architecture starts with understanding the problem. Adding AI should serve a clear purpose. In this episode: 0/ When ordinary code is the right solution 1/ Why a branching workflow does not automatically need an agent 2/ Where LLMs, skills, tools, and delegation fit 3/ How clarification helps with ambiguous requests 4/ Why an architect must be comfortable saying, “You don’t need AI for this.” CHAPTERS 00:00 Enterprise AI Architecture: Season 0, Episode 0 00:24 Why start with when NOT to use agents? 01:13 Processes, inputs, and outputs 02:54 The car analogy: unnecessary AI 04:00 When ordinary code is enough 05:03 CSV imports and database workflows 05:43 Adding invoice routing 06:34 An open-ended invoice request 07:47 LLMs, skills, tools, and delegation 09:32 Asking the user for clarification 10:36 Choosing the right kind of solution 11:46 Closing thoughts Where have you seen an AI agent proposed for something that ordinary software could handle?

.NET AI Community Standup: Interview Coach Evolves: MAF + GitHub Copilot SDK

* This content was pre-recorded. Bruno will join live in the chat! We just updated the Interview Coach! Join Bruno Capuano and Justin Yoo to explore the latest evolution of Interview Coach, a .NET sample built with Microsoft Agent Framework (MAF), now with GitHub Copilot SDK support. Discover how Copilot moves beyond the code editor to power an application where specialist agents review resumes, ask behavioral and technical questions, and deliver personalized feedback. The Copilot SDK handles model interactions and tool calls, while Agent Framework coordinates the agents and their handoffs. With shared MCP tools, a Blazor interface, and continued Microsoft Foundry support, this sample offers a practical starting point for your own agent-powered applications. ➡️ Explore the source code and continue learning with the companion walkthrough and hands-on workshop: https://aka.ms/mafinterviewcoach/repohttps://aka.ms/mafinterviewcoach/bloghttps://aka.ms/mafinterviewcoach/workshop 🔗 Links: https://learn.microsoft.com/en-us/collections/d4gkh1tee47wo?source=docs 🎙️ Featuring: Bruno Capuano https://www.linkedin.com/in/elbruno/, Justin Yoo https://www.linkedin.com/in/justinyoo #dotnet #MAF #GitHubCopilotSDK #Agents #AI

.NET MAUI Community Standup: Inside GnollHack: Cross-Platform Game Development with .NET MAUI

Join us for the next .NET MAUI Community Standup as we welcome Tommi and Janne, the creators of GnollHack! GnollHack is a cross-platform, turn-based rogue-like built on the classic NetHack codebase and modernized with animated graphics, music, sound effects, voiceovers, and touch-friendly mobile gameplay. We’ll explore how the team uses .NET MAUI to bring a deep, traditional roguelike experience to Android, iOS, and Windows. Hear about their development journey, the challenges of building a feature-rich cross-platform game, and the lessons they learned along the way. Bring your questions and join us live! 🔗 Links: https://www.theurlist.com/maui-standup-october26 🎙️ Featuring: Gerald Versluis (@jfversluis), David Ortinau (@davidortinau), Tommi Gustafsson, Janne Gustafsson #dotNETMAUI #dotNET #GameDev #GnollHack

Production Ready: Observability, Governance and Deployment

In the last episode of this series, we'll cover what you need before any of this runs somewhere real. OpenTelemetry traces and logs show exactly what the agent did on each turn. Purview handles governance and data protection. Evaluation gives us a way to tell whether quality holds as the SDK keeps moving. Then we deploy to Foundry Hosted Agents so the thing runs as a service instead of a console app. We close by walking through the full refresh-prompt workflow as a maintenance pattern worth stealing. 📌 This event is part of a series.

There's No Official Claude Agent SDK for C#. Here's What to Use Instead

There's No Official Claude Agent SDK for C#. Here's What to Use Instead

The Claude Agent SDK (the package that turns Claude into an autonomous coding agent with tools, permissions, and a conversation loop) only ships officially for Python and TypeScript. In C#, the closest thing is buried inside the regular Anthropic SDK: a `ToolRunner` helper that drives the tool-use loop for you. Here's how to build a real file-editing, command-running agent with it, and where the unofficial alternatives fit.
