## What it is
CefSharp is a .NET wrapper around the Chromium Embedded Framework (CEF) that lets you embed a full Chromium browser in WPF, WinForms, or offscreen .NET applications. It supports JavaScript interop, DevTools access, HTML5/WebGL, and headless browser automation.

## Use cases
- embed a web browser in a wpf application
- display html5 ui inside a winforms desktop app
- run headless chromium for web automation in c#
- execute javascript from .net and expose .net classes to javascript
- render remote web content in a native desktop application
- scrape or automate web pages with chromium in .net

## When to choose
- you need a full-featured, standards-compliant browser engine (HTML5, WebGL, PDF) inside a Windows .NET app
- you need deep JS/.NET interop or direct DevTools protocol access
- you want headless Chromium automation without a remote debugging port

## When to avoid
- you target macOS or Linux - CefSharp is Windows-only
- you only need a lightweight web view and can use WebView2 instead
- you cannot tolerate ~120 MB of added binaries in your app

## Facets
- artifact type: library
- maturity: active
- function: ui-components, web-framework, developer-tools
- domain: web-development, desktop-applications, cross-platform
- platform: windows, dotnet
- tags: chromium, cef, wpf, winforms, browser-control, webview, headless-browser, javascript-interop, desktop
