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.

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).

Financial Support

To continue developing/supporting the project I (@amaitland) am asking for financial contributions. Donations of any size are greatly appreciated!

Recurring contributions can be made through GitHub Sponsors it only takes a GitHub account and a credit card. Currently GitHub is doubling(!) all pledges so is very much the preferred method of donation. I can also take contributions through PayPal.

Now that I (@amaitland) am a stay at home dad your contributions are the only reason I'm allowed to continue working on the project. Without continued funding the time I currently spend on the project will have to be put into finding other paid work.
