This framework can be used to build applications that run across multiple platforms using their native toolkit, with an easy to use API. This will make your applications look and work as a native application on all platforms, using a single UI codebase.

For advanced scenarios, you can take advantage of each platform's capabilities by wrapping your common UI in a larger application, or even create your own high-level controls with a custom implementations per platform.

This framework currently supports creating Desktop applications that work across Windows Forms, WPF, MonoMac, and GTK#. There is a Mobile/iOS port in the works, but is considered incomplete.

This framework was built so that using it in .NET is natural. For example, a simple hello-world application might look like:

using Eto.Forms;
using Eto.Drawing;

public class MyForm : Form
{
	public MyForm ()
	{
		Title = "My Cross-Platform App";
		ClientSize = new Size(200, 200);
		Content = new Label { Text = "Hello World!" };
	}
	
	[STAThread]
	static void Main()
	{
		new Application().Run(new MyForm());
	}
}

or in a F# script:

#load ".paket/load/eto.platform.windows.fsx"
// see https://fsprojects.github.io/Paket/paket-generate-load-scripts.html

open Eto.Drawing
open Eto.Forms

type MyForm() as this =
    inherit Form()
    do
        this.Title      <- "My Cross-Platform App"
        this.ClientSize <- Size (200, 200)
        this.Content    <- new Label(Text = "Hello F# World!")

Eto.Platform.Initialize(Eto.Platforms.WinForms)
let app = new Application()
let form = new MyForm()
form.Show()

To begin creating apps using Eto.Forms, follow the Quick Start Guide.

Your project only needs to reference Eto.dll, and include the corresponding platform assembly that you wish to target. To run on a Mac platform, you need to bundle your app.

• Eto.dll - Eto.Forms (UI), Eto.Drawing (Graphics), and platform loading
• Eto.Mac64.dll - Lightweight Mac platform using .NET 6+ or mono
• Eto.macOS.dll - .NET 6+ platform for Mac (for use with the net6.0-macos target)
• Eto.WinForms.dll - Windows Forms platform using GDI+ for graphics
• Eto.Direct2D.dll - Windows Forms platform using Direct2D for graphics
• Eto.Wpf.dll - Windows Presentation Foundation platform
• Eto.Gtk.dll - Gtk+3 platform for Mac, Windows, and Linux.
• Eto.iOS.dll - Xamarin.iOS platform
• Eto.Android.dll - Xamarin.Android platform

• OS X: MonoMac or net6.0-macos
• Linux: GTK+ 3
• Windows: Windows Forms (using GDI or Direct2D) or WPF

These platforms are currently incomplete or in development. Any eager bodies willing to help feel free to do so!

• iOS using Xamarin.iOS
• Android using Xamarin.Android (Eto.Android)
