Uno Platform 5.5 - Automated App Packaging, .NET 9 RC2, OpenGL, WebView2 and more

Each release, we don’t just improve—we aim to revolutionize your development experience. For this release, we focused on drastically reducing the time and complexity required to package and distribute your cross-platform applications, in addition to a plethora of other productivity and performance features.

Our new App Packaging automates the process of bundling binaries, assets and dependencies into platform-specific installers for Linux, macOS and Windows on desktop. And, yes, that’s in addition to the seamless support we already provide for Mobile and Web packaging. It removes hours of frustration and dozens of manual steps which are typically needed when preparing your app for publishing, with just a few commands or clicks.

In addition to app packaging improvements, we are adding support for .NET 9 RC2 with WebAssembly, OpenGL Support, WebView2, New Skia Canvas, Combo Box and Templated Parent. It’s a big release, grab a coffee and read through our blog post.

At a glance, here are some of the new features:

  • Linux Snap, macOS .app and ClickOnce packaging support
  • GLCanvasElement for Desktop
  • SkiaVisual / SKCanvas support
  • WebView2 support on WebAssembly
  • .NET 9 RC2 support
  • .NET 9 WebAssembly bootstrapper support
  • Support for ComboBox.IsEditable, ComboBox.TextSubmitted, ComboBox.SelectionChangedTrigger
  • Many TemplatedParent propagation fixes
  • Support for ColorHelper and KnownColors
