History
Avalonia, originally named Perspex,[15] was first developed by Steven Kirk, with its initial commit made on 5 December 2013. The framework was conceived with the aim of creating a cross-platform UI framework, inspired by Windows Presentation Foundation (WPF).[16]
Avalonia became part of the .NET Foundation[17] on 1 April 2020,[18] and left on 20 February 2024.[19]
On 24 June 2025, Avalonia announced a $3 million sponsorship from Devolutions to support the continued development of the framework while maintaining its free and open-source nature.[20]
