## What it is
SunnyUI.NET is an open-source C# WinForm UI control library, utility class library, and multi-page development framework built on .NET Framework 4.0+ and modern .NET (6/8/9/10). It offers 70+ custom controls styled after Element UI, 17+ themes with a theme manager, plus extension and tool classes.

## Use cases
- build modern-looking WinForm desktop apps in C#
- add themed buttons, dropdowns, and data grids to a .NET desktop app
- create dashboards with charts and gauges in WinForms
- switch themes dynamically in a Windows desktop application
- develop multi-page WinForm applications with a page framework
- replace default WinForm controls with Element-style UI components

## When to choose
- you are building a Windows desktop app with WinForms and want polished, modern controls
- you need built-in themes, charts, and industrial gauges without extra dependencies
- you target .NET Framework 4.0+ or modern .NET 6/8/9/10
- you want a multi-page framework and utility/extension classes bundled together

## When to avoid
- you are building WPF, UWP, Avalonia, or web applications
- you need a permissive license for commercial use without authorization (GPL-3.0, commercial use requires a paid license)
- you need cross-platform desktop UI beyond Windows
- you require a minimal set of controls and find a 70+ control library too heavy
