Where
Online, on an open live stream
The stream is open to everyone. Registered guests get the link by email, and it also goes up on this page before the day.
What’s on
A keynote, talks and a live Q&A
Each talk is 45 minutes including Q&A, and there are five minutes between sessions. The Avalonia team closes the day.
For speakers
We’re looking for talks built on real experience
Community slots are open. Propose a 45-minute talk, Q&A included, for the people who design, build and maintain applications with Avalonia. It’s online, so you present from wherever you are. First-time speakers are as welcome as experienced ones.
Topics we’re looking for
Architecture
MVVM, composition, navigation, modularity and the patterns that held up in production.
UI and product
Interface design, theming, accessibility and the details that make an app feel finished.
Performance
Startup, rendering, memory and profiling, with the measurements to back it up.
Cross-platform
Desktop, mobile and browser targets, packaging, deployment and CI/CD.
Migrations
What moving from WPF, Windows Forms or other frameworks actually took.
Ecosystem
Open-source libraries, tooling and practices that scale across teams.
Proposal tips for speakers
Bring a story from production. We’re looking for people to share what they built with Avalonia, what broke and what they’d do again.
What makes a strong proposal
Name a problem, the context it came up in, what you learned and the level the talk is pitched at. A specific story beats a broad survey: “Taking a 15-year-old WPF line-of-business app to macOS” tells us far more than “Migrating to Avalonia”.
Pitch it for 45 minutes
That’s long enough to show real code and real measurements, and short enough that the talk needs a clear point. Q&A is part of the 45 minutes, so leave room for questions.
AI has a place here too
LLM features in your apps, MCP servers that let agents work with an application, or an honest look at what coding agents can and can’t do when building and testing Avalonia apps. We care less about general introductions to AI than about what you built and what you learned.
