.NET 10 Support, Faster XAML Editing, and Improved Authentication
Support for system proxy when signing in
The Avalonia extension adds support for .NET 10 templates, enabling new cross-platform apps built on the latest .NET features and performance upgrades.
.NET 10 template support
The Avalonia extension now supports .NET 10 project templates, letting you create new cross-platform apps that take advantage of .NET 10’s latest performance and language improvements.
.NET 10 template support
The Avalonia extension now includes full support for .NET 10 project templates. Create new cross-platform applications targeting the latest .NET release with all the performance improvements and language features .NET 10 brings to your Avalonia projects.

Performance improvements
The XAML language service now responds faster when editing large files, opening projects, and switching between documents. Reduced memory consumption and optimized background analysis mean a smoother, more responsive editing experience even in complex solutions.
Improved editor experience
We've addressed numerous issues across the XAML processing, including fixes to the syntax classifier for more accurate code coloring, improvements to code completion accuracy, and enhanced diagnostic reporting that catches errors more reliably and provides clearer messages.
Support for system proxy when signing in
The extension now respects your system proxy settings during authentication. If you're working behind a corporate proxy, you can now sign in to Avalonia services without additional configuration or workarounds.

Authentication resiliency
Authentication tokens are now automatically refreshed in the background, so you can keep Visual Studio open for extended periods without being interrupted by sign-in prompts.
Updated minimum Visual Studio version
Visual Studio 2022 version 17.12 or later is now required to use the Avalonia extension. This update ensures compatibility with the versions that Microsoft supports.
XAML styler workaround
It's now possible to force the XAML Styler extension to run whenever a file is saved using the new "Advanced" setting. The XAML Styler must be installed and configured separately.
