*Talk by Joakim Ahnfelt-Rønne and Michael Flænø Werk* What's the set of features you need to build a production webapp? In this talk we build a minimal but feature-complete (or is it?) webapp in our functional-imperative hybrid web language, Firefly, packing in the features we think are essential: Route-based bundling, server side rendering with hydration, declarative DOM, scoped CSS, WebSockets, serialization, typed RPC, and more. *As usual, there's mingling at the local bar after the talk.*

**Welcome to .NET Skåne February 2026 edition!** We are very happy to invite you to Ductus and an evening with our MVP Tore Nestenius! Join us for an evening filled with two insightful presentations from Tore and one surprise talk from Jonah Andersson as well as networking and great company. This event is free to attend and there will be free drinks and food. We hope to see you there! **IMPORTANT**: If you have signed up to the event but can't make for some reason please cancel your spot in good time before the event so the spot is free for someone else to attend. **Agenda:** **How Does a Coding Agent Work?** (Tore Nestenius) Coding agents are increasingly used to automate software tasks, yet how they actually work is often treated as a black box. This talk breaks a coding agent down into its core mechanics: how it is structured, how it communicates with a language model, and how a text-only model can read and modify real source code. We will cover: \* what a coding agent is, mechanically \* how agents communicate with language models \* how tools and MCP calls are executed \* how a text-only model works with source code \* how to build a basic coding agent in C# **The Anatomy of MCP Server: A Developer’s Perspective** (Jonah Andersson) What does it really take to build an MCP server from scratch? In this session, we learn the anatomy of the Model Context Protocol (MCP) in the perspective for development from local to cloud — from how MCP different from API, how to build it, test it locally and deploy it on an app hosted on Azure. Using Azure Functions with the MCP Tool Trigger extension for .NET, in this short session you will learn how to build a working MCP server step by step. You’ll leave with a clear mental model of how MCP servers work under the hood and the confidence to build your own. **The Data Protection API: The Hidden Security Hero in ASP.NET Core** (Tore Nestenius) The Data Protection API protects authentication cookies, anti-forgery tokens, and other sensitive data in ASP.NET Core. It often “just works” in development, but in production it can cause broken logins and random sign-outs after redeployments or when scaling out behind a load balancer. This session explains Data Protection from a production-first perspective. We will cover how key rings are created and rotated, why multi-instance setups fail, how purpose strings affect isolation and interoperability, and how to safely share authentication cookies across services. **About the speakers:** [Tore Nestenius](https://www.linkedin.com/in/torenestenius) Tore is a Microsoft \.NET MVP\, an Azure\-certified developer\, and an expert in areas like CQRS and event\-sourcing\, as well as web security and IdentityServer\.

In this session we will show how bootable containers work and what to be aware of. Talk 2: **We Broke Free From Cloud-Managed Kubernetes: Now What?** Speaker: Kārlis Akots Gribulis and Per Hedegaard Christiansen from Saxo Bank Have you ever wondered what happens after moving from cloud-managed Kubernetes to self-hosted clusters? One year into Saxo Bank’s journey, we’re sharing the full story: what worked, what surprised us, and what we would do differently.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
