CefSharp
.NET bindings for the Chromium Embedded Framework, letting a WPF or Windows Forms application embed a Chromium browser control.
CefSharp is a lightweight .NET wrapper around the Chromium Embedded Framework (CEF), letting an application embed Chromium from C#, VB or any other CLR language. About 30% of its bindings are written in C++/CLI, with the majority of the codebase in C#.
It ships separate browser control implementations for WPF and Windows Forms, plus an off-screen rendering mode and a WPF host for the WinForms control, and is distributed as NuGet packages that include everything needed to embed Chromium in a .NET or CLR application.
CefSharp is BSD licensed, so it can be used in both proprietary and free or open-source applications.
