## What it is
Eto.Forms is a cross-platform GUI framework for .NET that lets you build desktop (and eventually mobile) applications with a single UI codebase. It renders using each platform's native toolkit (WPF, Windows Forms, MonoMac, GTK#) so apps look and behave natively on every OS.

## Use cases
- build a cross-platform desktop app in C#
- write one UI codebase that runs on Windows, Mac, and Linux
- create native-looking .NET GUI applications
- share UI code between desktop platforms in .NET
- build a desktop app without learning each platform's toolkit
- wrap platform-specific features around a common UI

## When to choose
- you want truly native look and feel on each platform from one codebase
- your team works in .NET/C# or F#
- you need to target Windows, macOS, and Linux desktops
- you want a mature, permissively-licensed alternative to Avalonia or MAUI

## When to avoid
- you need a production-ready mobile (iOS/Android) target today - the mobile port is incomplete
- you want pixel-perfect identical rendering across platforms rather than native styling
- you're building web or console-only applications

## Facets
- artifact type: framework
- maturity: active
- function: gui, ui-components, mobile-framework, desktop-framework
- domain: cross-platform, desktop-applications, mobile-development, web-development
- platform: windows, dotnet, cross-platform
- tags: eto-forms, native-ui, wpf, winforms, gtk, monomac, single-codebase, macos, linux, desktop, mobile
