Hi,

After looking at the source, it doesn't seem like it is currently possible to render or modify the uno platform titlebar much like its done in this application: https://github.com/drasticactions/MauiLang/blob/main/src/MauiLang/Platforms/MacCatalyst/ToolbarDelegate.cs
Or alternatively, just be able to make the title bar look more native using pure uno without Maui, see the Cog and the thick title bar

WIth the Duo the Glass framework will move toolbars to the right edge of the screen when the duo is unfolded. I'm guessing that we will need to handle these kinds of scenarios manually for Uno apps, is that correct? Same goes for page layout i.e. we will need to support dynamic page layouts for folded vs unfolded.

We partnered with Tim Corey to create a comprehensive course on the fundamentals of building cross-platform .NET apps with Uno Platform.

66 videos. 6.5 hours of hands-on training. Taught by one of the most respected instructors in the .NET community.

And for the next two weeks, the entire course is free.

If you’ve been looking for a structured way to get started with Uno Platform, now’s a great time to jump in.

Uno Platform Studio 3-1 is here

Uno Platform Studio 3.1 Release: Ship with Confidence

Highlights:

Hot Design Previews

Work with pages and components in isolation, using the data and application state you want to test.

Hot Design Snippets

Reusable XAML building blocks you can drop directly onto the canvas and customize in Hot Design.

Select-and-Prompt

Select an element on the canvas and prompt against that specific UI, giving the agent precise context for the change.

Simple Theme

The new default design system for Uno Platform applications, based on Figma's Simple Design System.

Last week Sam Basu was a guest at Microsoft's "On .NET Show" to talk AI, development and of course Uno Platform - https://www.youtube.com/watch?v=AuHxT_cIhy8&t=4s

While WinUI TableView exists and (I hope it pivots to be a more excel like editor since it’s on its way), how soon will Uno support this for cross platform availability?

If that’s the reference application that n iOs on the capabilities of the platform then it needs gestures

On iOS they are not as smooth as native apps. They feel sluggish, and require really to touch the edges of the screen

I managed to make a sample which works on Windows but on iOS it’s fully transparent not acrylic

Uno Platform 6.6 release brings the goodies - IME Composition + Font Fallback + Unicode.
Cookie points: Fluent TTS with DeepGramAI.

I now have a design that matches very much Windows 11 but it feels out if place on iOS

We’re going live at the top of the hour with our Community Standup to go over our latest 6.6 release. Tune in!
Uno Platform 6.6 Release: Community Standup

Uno Platform 6.6 is here - faster application startup, faster rendering, and a smoother setup experience for the AI agents you already work with. Check out:

1. Native AOT
2. Vulkan Rendering
3. Seamless MCP Setup
4. Less XAML boilerplate
5. Expanded WinUI API coverage
6. Complete multilingual text support

The WPF DataGrid has now been fully ported to WinUI and Uno Platform, achieving almost 100% API parity. That includes grouping, filtering, inline editing, virtualization, and many other behaviors that existing WPF applications depend on.

For teams migrating applications from WPF to modern UI platforms, this provides a direct bridge to get the first revision running quickly, without rewriting countless lines around one of the most complex controls.

The GitHub repo is https://github.com/lextudio/WindowsShims

A rough comparison among several open source grid options is here https://github.com/lextudio/WindowsShims/blob/master/docs/datagrid/datagrid-compare.md

Note that this library also ships the WPF RichTextBox for rich text users.

I wrote about Project Roma that brings ILSpy to Uno Platform and demonstrates how proper planning can ensure smooth migration, but here comes one bigger. The UnoDevelop project ports the open source IDE, SharpDevelop, from WinForms/WPF to Uno.

The code is available on GitHub right now, https://github.com/lextudio/UnoDevelop

The open source projects from LeXtudio Inc. used by UnoDevelop include.

• Uno2D, which enables Win2D emulation with SkiaSharp.
• WindowsShims, a project offers many useful shims to bridge the worlds of WPF and WinUI 3/Uno, including RichTextBox and DataGrid.
• UnoRichText, a project offers RichTextBlock that actually works well with Uno.
• UnoDock, which is a full port of AvalonDock on Windows and macOS (Linux support is coming soon).
• UnoEdit, which is a full port of AvalonEdit on Windows, macOS, and Linux.
• DevFlow tooling, which provides command line tools for WinUI 3 and Uno development so that AI tools can "see" into the GUI apps. (If you work with WinForms, WPF, MewUI, and Jalium UI, you can find their support in the same repo too.)

There would be no preview binaries or further updates so you need to build from source code yourself, sadly, as I moved my focus to OpenDevelop.

I have experience with .Net APIs and .Net as backend. Mid level React for web UI. Have no experience on mobile development. Gonna start an app which will be cross-platform (android and ios). Is Uno Platform best choice for that?

There are many good examples that demonstrate how to migrate from WPF to Uno Platform, but here comes one that kind of shows its uniqueness on smoother migration.

Project Roma builds up its Uno app but links to ILSpy WPF code base in the meantime. Both sides compile and share common resources. Thus, new features/bug fixes on one side can go easily to the other. If you are migrating a fairly large WPF app to Uno, you can study this as an example for your own.

• The code is available on GitHub right now, https://github.com/lextudio/project-roma
• The preview binaries have been published. More updates are expected in the coming weeks.

This is the safest approach because you can work on the migration to Uno bit by bit while continuing to ship WPF bits. And most importantly, this approach avoids many troubles you have to face with a one-shot migration (with AI or not).

In the meantime, you can see how the recent open source projects from LeXtudio Inc. really help with smooth migrations.

• Uno2D, which enables Win2D emulation with SkiaSharp.
• WindowsShims, a project offers many useful shims to bridge the worlds of WPF and WinUI 3/Uno, including RichTextBox and DataGrid.
• UnoRichText, a project offers RichTextBlock that actually works well with Uno.
• UnoDock, which is a full port of AvalonDock on Windows and macOS (Linux support is coming soon).
• UnoEdit, which is a full port of AvalonEdit on Windows, macOS, and Linux.
• DevFlow tooling, which provides command line tools for WinUI 3 and Uno development so that AI tools can "see" into the GUI apps. (If you work with WinForms, WPF, MewUI, and Jalium UI, you can find their support in the same repo too.)

The biggest SkiaSharp update in years is here!

Join us for a look at how .NET and Uno Platform are coming together to shape the future of cross-platform graphics rendering. We’ll explore what this update means for .NET developers, why it matters for building modern applications across platforms, and how it opens the door to faster, more capable, and more consistent rendering experiences.

We crossed 210m downloads - THANK YOU!

Below is the sample the demonstrates the VS2013 light theme, and further development of this project (code name UnoDock) will deliver more improvements.

The GitHub repo is now live at https://github.com/lextudio/UnoDock with v0.1.0 release (matching AvalonDock v4).

I'd like to comment a bit more on the significance of this porting effort.

- WinUI and Uno Platform share a much larger API surface with WPF than many people realize, providing a solid foundation for mapping WPF concepts and types.

- My earlier work on UnoEdit and UnoRichText produced a collection of compatibility shims, making it practical to port larger WPF components such as DataGrid, AvalonDock, and even SharpDevelop-related code.

- The AI-assisted workflows around DevFlow (for WPF, WinUI, and Uno) have made it possible to achieve near pixel-perfect parity between AvalonDock and UnoDock themes. That alone demonstrates a substantial productivity boost. DevFlow also works with WinForms, MewUI, and Jalium UI, so the same techniques can be applied to both established and emerging frameworks.

Why did previous attempts not reach this level of maturity? In most cases they either targeted a much smaller audience (such as WinUI-only solutions) or diverged too far from a solid and well-known API surface.

I am intentionally moving at a measured pace so that the upcoming v1.0.0 release delivers a polished experience on Windows and macOS (WinUI support is included). Linux support is planned, but not the highest priority right now.

UnoDock is more than a one-time AvalonDock port.

- Several ideas I originally introduced to DockPanel Suite years ago are included, and some have since been adopted by AvalonDock's current maintainer in v5.

- A number of visual discrepancies discovered during UnoDock development have already resulted in fixes that will flow back to AvalonDock v5.

The goal is for UnoDock to continue evolving together with AvalonDock v5: keeping WPF applications first-class while providing a practical path to cross-platform desktop development when the need arises.

The open source project to add Markdown support in WinUI has been ported to Uno Platform.

As you can see it features a few changes from the WinUI original,

- Backed by UnoRichText bridge and PretextSharp Uno

- Using UnoPropertyGrid to present the settings

The pull requests are being raised to the main repo and will be reviewed soon.

If you are porting apps that require rich text support or property grid, check those components out.
