Woke up to the news that Claude Fable has been removed, so I decided to go outside.

Avalonia 12 support was added to Mapsui 5.1.0-beta.7 šWe had quite some requests for this.
Can I have some cheers from the Avalonia community?

1007 days since we released Avalonia 11.

The particular 'contributor' has been vibe-coding slop knockoffs of our products, and is now complaining that we won't share our roadmap with him...
There's a limited market for vibe-coded slop alternatives. Customers ultimately want quality and stability.
I'm so done with OSS. I do a refactoring to fix perf, it has a bug due to a typo. Bug is reported and a huge AI-slop PR arrives. I push one-line fix for the typo. Fast forward a month, the vibe-coder complains that his PR isn't getting traction and accuses for copying his AI fix.

To be clear. @kekekeks isn't the contributor throwing our slop. He's on the receiving end of it.

Huge kudos to Tim and Javier, whose work made this happen.
Supporting the broader .NET ecosystem through initiatives like this is a great example of what weāre building Avalonia to do.
A stronger ecosystem benefits everyone.

I wanted to see how difficult it would be to update MonoDevelop to use Avalonia.
Turns out, it's easier than I imagined!
Hugely boosted by using @Actipro, NetCoreDbg, and the existing code we've written for Accelerate.

I've been building an AI chess coach using @AvaloniaUI, powered by @OpenRouter.
I can swap between different LLMs for gameplay and coaching advice, and it's already helping me improve!

This was a ton of fun. I spent more time tweaking the banner animation than anything else!
It's wild how productive you can be when you lean into the tools available today.

Our CEO 'built' a stunning Avalonia app, between emails, meetings and other boring tasks.
He used Claude Code, Stitch and the Avalonia DevTools MCP server to build something that looks 10x better than the existing samples.

One more example of @DevolutionsInc taking sustainable FOSS seriously and setting the standard the rest of us should be aspiring to!
If more organisations treated open-source sustainability the way Devolutions does, the entire ecosystem would be healthier.

Weāve closed significant new deals that will solidify @AvaloniaUI as the future of .NET UI.
I also attended .NET Conf China, which was the best community-run event Iāve ever attended.

I spoke with @maddymontaquila last month about Aspire, having known almost nothing about it.
I had a 12-hour flight yesterday, so I decided to migrate our customer admin portal to use it.
Really impressed so far! I can 100% see how itāll help the team. ā¤ļø
