What people are saying about Avalonia


The dotTrace/dotMemory team

We’ve been considering making our standalone profilers for .NET cross-platform for some time now, and we’ve been actively looking for a UI framework to use. As our tools use WPF, Avalonia was an easy choice for us. It is an impressive technology which has seen tremendous growth in recent years, and it feels mature enough to be used for production code. And we greatly appreciate the quick and helpful support we have had from the Avalonia developers who have addressed our questions.
