UnoDock

UnoDock is a desktop-first port of AvalonDock to Uno Platform and WinUI 3.

Current scope:

• Target Uno Skia Desktop on Windows and macOS in initial builds.
• Do not target Linux yet
• Do not target WinUI 3 yet
• Do not target mobile during the bootstrap phase (v0.x.x).

Current scope:

• Target Uno Skia Desktop.
• Do not target mobile during the bootstrap phase (v0.x.x).

Supported Platforms

• Windows 11 (Windows 10 may work but is not a primary target)
• macOS, 3 most recent versions from 2023-2025

WinUI 3 support is planned later.

Linux support is planned later.

If you are looking for support of a specific platform, business sponsorship is the way to accelerate that work. Please reach out to us at homepage.

Get Started

Several NuGet packages are available:

• The core docking manager component.
• VS2013 theme.
• VS2010 theme.

Default usage

Install the core package and one theme package:

dotnet add package LeXtudio.UnoDock
dotnet add package LeXtudio.UnoDock.Themes.VS2013

Load the theme resources before the window XAML is initialized. This makes the UnoDock_VS2013_* brushes available to the docking manager and to any surrounding UI that wants to match the same palette.

using Microsoft.UI.Xaml;
using UnoDock.Themes.VS2013;

public sealed partial class MainWindow : Window
{
    public MainWindow()
    {
        Application.Current.Resources.MergedDictionaries.Add(
            new Vs2013LightTheme().ThemeResourceDictionary);

        InitializeComponent();
    }
}

Then declare a DockingManager and provide an initial layout. UnoDock follows the AvalonDock model names, so documents live in LayoutDocumentPane and dockable tool windows live in LayoutAnchorablePane.

                        <dockLayout:LayoutAnchorable Title="Properties"
                                                     ContentId="properties">
                            <TextBlock Margin="8" Text="Selected item properties" />
                        </dockLayout:LayoutAnchorable>
                    </dockLayout:LayoutAnchorablePane>

                </dockLayout:LayoutPanel>
            </dockLayout:LayoutRoot>
        </dock:DockingManager.Layout>
    </dock:DockingManager>
</Window>

Use stable ContentId values for every document and tool pane. They are used by layout persistence and make it possible to restore panes back to the right application content later.

Study the sample project for layout save/load, floating window diagnostics, and a fuller Visual Studio-style shell.

Current Status

Early preview (v0.x.y) releases are available on NuGet.

The API is not yet stable and may change without a major version bump. Feedback is welcome to help shape the future of UnoDock.

TODO Items Before v1.0.0

• More themes
• Logical tree improvements
• Accessibility support (screen readers, keyboard navigation, etc.)
