Consolonia.ManagedWindows

Managed windows and storage integration for Consolonia/Avalonia apps running in the console.

This module provides:

• File and folder pickers implemented as managed windows (open, save, pick folder).
• An IStorageProvider implementation that plugs into Avalonia (ConsoloniaStorageProvider).
• Simple wrappers for system files/folders (SystemStorageFile, SystemStorageFolder).
• Theme resources for managed windows (Modern and TurboVision) with auto‑inclusion via AutoManagedWindowStyles.

Getting started

1. Enable the Consolonia storage provider in your app startup:

using Avalonia;
using Consolonia.ManagedWindows.Storage;

public static class Program
{
    public static void Main(string[] args)
    {
        BuildAvaloniaApp().StartWithClassicDesktopLifetime(args);
    }

    public static AppBuilder BuildAvaloniaApp() =>
        AppBuilder.Configure<App>()
                  .UsePlatformDetect()
                  .UseConsoloniaStorage(); // <= enables Consolonia storage dialogs
}

2. Include Managed Windows styles (Modern/TurboVision). The easiest way is to auto‑include styles based on your Consolonia theme family:

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:themes="clr-namespace:Consolonia.Themes;assembly=Consolonia.ManagedWindows">
  <Application.Styles>
    <themes:AutoManagedWindowStyles/>
  </Application.Styles>
  
  
</Application>

Alternatively, include styles explicitly:

<StyleInclude Source="avares://Consolonia.ManagedWindows/Themes/Base.axaml" />


<StyleInclude Source="avares://Consolonia.ManagedWindows/Themes/TurboVision/TurboVision.axaml" />

Using the pickers (Avalonia IStorageProvider)

All standard Avalonia storage APIs are supported through TopLevel.StorageProvider.

Open files:

var topLevel = TopLevel.GetTopLevel(this)!;
var files = await topLevel.StorageProvider.OpenFilePickerAsync(new FilePickerOpenOptions
{
    Title = "Open files",
    AllowMultiple = true,
    FileTypeFilter = new[]
    {
        new FilePickerFileType("Text") { Patterns = new[] { "*.txt", "*.md" } }
    }
});

Save a file:

var topLevel = TopLevel.GetTopLevel(this)!;
var file = await topLevel.StorageProvider.SaveFilePickerAsync(new FilePickerSaveOptions
{
    Title = "Save as",
    SuggestedFileName = "document.txt"
});

if (file is not null)
{
    await using var stream = await file.OpenWriteAsync();
    // write your content
}

Pick a folder:

var topLevel = TopLevel.GetTopLevel(this)!;
var folders = await topLevel.StorageProvider.OpenFolderPickerAsync(new FolderPickerOpenOptions
{
    Title = "Choose a folder",
    AllowMultiple = false
});

You can also resolve paths directly through the provider:

var file = await topLevel.StorageProvider.TryGetFileFromPathAsync(new Uri("file:///path/to/file.txt"));
var folder = await topLevel.StorageProvider.TryGetFolderFromPathAsync(new Uri("file:///path/to/folder"));

What’s inside

• Storage/StorageStartupExtensions.cs – AppBuilder.UseConsoloniaStorage() extension.
• Storage/ConsoloniaStorageProviderFactory.cs – wires IStorageProvider for a TopLevel.
• Storage/ConsoloniaStorageProvider.cs – implements IStorageProvider using managed dialogs.
• Controls/FileOpenPicker.*, FileSavePicker.*, FolderPicker.* – managed window dialogs.
• Controls/SystemStorageFile.cs, SystemStorageFolder.cs – system I/O wrappers.
• AutoManagedWindowStyles and resources in Themes/ – styles for managed windows.

Samples

See src/Consolonia.Gallery for examples of using pickers in a running Consolonia app.

Dependencies

• Avalonia 11+
• Iciclecreek.Avalonia.WindowManager (for managed windows)
