CefSharp lets you embed Chromium in .NET apps. It is a lightweight .NET wrapper around the Chromium Embedded Framework (CEF) by Marshall A. Greenblatt. About 30% of the bindings are written in C++/CLI with the majority of code here is C#. It can be used from C# or VB, or any other CLR language. CefSharp provides both WPF and WinForms web browser control implementations.

CefSharp is BSD licensed, so it can be used in both proprietary and free/open source applications. For the full details, see the LICENSE file.

If you like and use CefSharp please consider signing up for a small monthly donation, even $25 can help tremendously. See Financial Support for more details.

Releases

Stable binaries are released on NuGet, and contain everything you need to embed Chromium in your .Net/CLR application. For usage see the Quick Start guide or checkout CefSharp.MinimalExample project for basic demos using the CefSharp NuGet packages.

CefSharp.WinForms
CefSharp.Wpf
CefSharp.OffScreen
CefSharp.Wpf.HwndHost (A HwndHost based WPF implementation, similar to hosting the WinForms version in WPF, supports data binding, airspace issues apply).

Documentation

See the CefSharp.Wpf.Example or CefSharp.WinForms.Example projects for example web browsers built with CefSharp. They demo most of the available features.
See the CefSharp.MinimalExample project for a basic demo of using the CefSharp NuGet packages.
See the General Usage Guide in help getting started/dealing with common scenarios.

Branches & Forks

This is the official CefSharp fork, as maintained by the CefSharp community. You can also view the entire network of public forks/branches.

Development is done in the master branch. New features are preferably added in feature branches, if the changes are more than trivial. New PR's should be targeted against master.

When a new release is imminent a release branch is created. We try to avoid making public facing API changes in release branches (Adding new features is fine, just not breaking changes).

CI Builds
Every commit on master produces a Nuget package. Use at your own risk!

Release Branches

With each release a new branch is created, for example the 92.0.260 release corresponds to the cefsharp/92 branch. If you're new to CefSharp and are downloading the source to check it out, please use a Release branch.
