Learning .NET MAUI is one thing. Learning how to build MAUI apps well is another.
In this hands-on workshop, Gerald Versluis will cover APIs, JSON, maps, location and theming—alongside the practices and workflow used by the .NET MAUI team. 🐒

2024 began with MAUI Day Cologne.
The name had changed, but the purpose was familiar: bringing developers together to learn, share practical experience and help shape the future of .NET MAUI.

My having-fun-gauge is peaking at the #MAUIday in Kraków ... thank you so much for joining ... and thank you very much for having me ❤️.
We can’t get enough of looking at beautiful .NET MAUI apps all day! But have you actually _observed_ them?
@flashoware.bsky.social joins us today to tell us exactly how to do that; observability for .NET MAUI

My having-fun-gauge is peaking at the #MAUIday in Kraków ... thank you so much for joining ... and thank you very much for having me ❤️.
I am looking forward to the #dotnet #MAUIDay in Kraków ... a lovely community in a lively city ... and premiering my first talk on Observability and .NET MAUI.
App crashed. No logs. No clue why 😬
At #MAUIDay, Stefan Pölz shows how to fix that with real observability in .NET MAUI:
- Logs, metrics, traces (o11y)
- OpenTelemetry in practice
- Aspire & Sentry
Less guessing. More insight.

What does it really look like when the people building .NET MAUI make an app?
At #MAUIDay Cologne, Stéphane Delcroix and engineers from the MAUI team will code live on stage — sharing their prompting habits, quick decisions, and a bit of productive chaos.
Ok.
A lot of chaos.
