Got a quick question? Jump on Gitter

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.


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 FAQ #8.


  • 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.
  • See the Wiki for work-in-progress documentation
  • See the FAQ for help with common issues
  • Upgrading from an earlier version of CefSharp? See the ChangeLog for breaking changes and upgrade tips.
  • CefSharp API generated from the source code comments.


If you have a very simple question please start by asking it on Gitter. Please keep the Issue Tracker for Bugs only please! Before submitting a PR please read CONTRIBUTING

Stackoverflow is generally where questions should be asked, please search before posting, thanks!

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.

Note Due to so many Forks - Github can't process them through the Network Graphs Section so, if you need to do a search use the following: cefsharp fork:true and it will be able to process all of the forks.

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 53.0.1 release corresponds to the cefsharp/53 branch. If you're new to CefSharp and are downloading the source to check it out, please use a Release branch

Financial Support

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

73.0.0 Release: Bountysource

Recurring contributions can be made through BountySource Salt or contact me if you'd like to donate 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.
