Avalonia UI

We’re teaming up with Google’s Flutter team to bring Impeller to .NET Impeller is Flutters new GPU-optimised renderer, replacing Skia for better performance on mobile and embedded devices. This is what open collaboration looks like 🚀 avaloniaui.net/blog/avalonia-…

Nobody asked for it, but we thought "why stop at WPF?" Introducing Win16-lonia. A static recompiler for Win16 and MSDOS apps to Avalonia. Yes, we know what day it is. Yes, this is real. Code coming soon. 😂

Avalonia 12.0.0 RC2 is here. Your feedback on RC1 drove real improvements, and we're getting very close to a stable release. Give it a spin and let us know how you get on! github.com/AvaloniaUI/Ava…

@_RaphaelFrei Looks lovely!

🚀 Starting a new PROJECT today! So, Day #1 working on my new video editor with Avalonia. The idea is "simple": Create a video editor focused on users that don't requires complex editors like Premiere. The app will offer timeline, video cuts, merge videos (without rendering), watermarks and image overlays. It's just day one developing, but I've managed to get some code from a freeware I wrote a couple years ago and started playing with it. The idea is to offer a single payment - Around $20, or free version with app watermark and limited-export at 1080p. (Pages are on two-languages, because I'm still working on translations)

The team at @icons_8 have taken Lunacy to the browser! This is the coolest Avalonia on WASM app we've seen yet! lunacyapp.com

@michaldobro @Carlos74962907 Great to hear you’re seeing the performance improvements!

@Carlos74962907 @AvaloniaUI My experience: - finally smooth scrolling on Android, v11 is unusable - yesterday I noticed during profiling that v12 has 3x less cpu usage when running axml animation

Interesting experiment 👀

What if you could script cross-platform desktop GUIs in #PowerShell using Avalonia UI instead of WinForms? AvaloniaUIShell just came out, and it's the real deal! Try it now: github.com/mdgrs-mei/Aval…

@slace MCP support is part of the paid tier.

@AvaloniaUI want to confirm - the accelerate MCP server isn't supported on the community licensing tier is it? I'm keep to try it on an OSS project

@fexdev 12.x but not in 12.0

@AvaloniaUI congrats! will impeller still be in 12?
