ℹ️ Notes

• CefSharp requires a minimum of Visual C++ 2015. See https://github.com/cefsharp/CefSharp/issues/1983 for details. You can bin deploy the VC++ dependencies, read the FAQ for more details. VC++ 2017/2019 are backwards compatible. For a list of files included in the packages see https://github.com/cefsharp/CefSharp/wiki/Output-files-description-table-%28Redistribution%29
• Chromium has removed support for Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008. See https://chrome.googleblog.com/2015/11/updates-to-chrome-platform-support.html
• Starting in June 2019 Google will block logins from CEF based browsers to Google Services, this includes Gmail, Drive, Docs, see https://security.googleblog.com/2019/04/better-protection-against-man-in-middle.html?m=1 for further discussion see https://groups.google.com/a/chromium.org/d/msg/embedder-dev/STyM5ZNTHMM/POj1v_cqBgAJ

Notes

• CefSharp requires Visual C++ 2015. See https://github.com/cefsharp/CefSharp/issues/1983 for details. You can bin deploy the VC++ dependencies, read the FAQ for more.
• Chromium has removed support for Windows XP, Windows Vista, Windows Server 2003 and Windows Server 2008. See https://chrome.googleblog.com/2015/11/updates-to-chrome-platform-support.html
• Starting in June 2019 Google will require OAuth authentication when accessing web services that rely only Google Account Data, this includes Gmail, Drive, Docs, see https://security.googleblog.com/2019/04/better-protection-against-man-in-middle.html?m=1 for further discussion see https://groups.google.com/a/chromium.org/d/msg/embedder-dev/STyM5ZNTHMM/POj1v_cqBgAJ
• Due to licensing issues default builds do not support proprietary codecs like H264/AAC, sites like Netflix/Twitter/Instagram/Facebook won't play video/audio. See #1479 for more info. MP3 audio is supported.
• Anyone new to CefSharp should read the General Usage Guide
• This project uses GitLink for better debugging, you can step directly into much of the project source directly from Visual Studio see #1680 for details on how to enable GitLink
• WPF now has touch support which is enabled by default. Support for Stylus is not enabled by default, see https://github.com/cefsharp/CefSharp/issues/228#issuecomment-489065987 for further details
• CEF now supports Print Preview see #2332 for details on how to enable it
• Legacy Javascript binding registered JavaScript objects no longer get lost when navigating to another domain.
• Both the WPF and OffScreen versions have disable-gpu-compositing set by default to workaround https://bitbucket.org/chromiumembedded/cef/issues/2833/osr-gpu-consume-cpu-and-may-not-draw and https://bitbucket.org/chromiumembedded/cef/issues/2823/osr-on-a-monitor-at-125x-scale-onpaint

Known Issues

• WinForms when running on Windows 10 Anniversary pressing certain key combinations freezes the browser see #1822 The issue has been reported upstream, there are workarounds listed in #1822
• Browser goes blank if used in combination with WPF TabControl see #2779
• CefSettings.IgnoreCertificateErrors no longer works, use the ignore-certificate-errors command line arg as a workaround or alternatively use OnCertificateError to selectively allow a certificate and/or display a dialog to your users see https://stackoverflow.com/a/35564187/852806 for an example.
• When loading a WebM file (or any mimetype that supports range headers) the request is cancelled unexpectedly and the video fails to load see https://bitbucket.org/chromiumembedded/cef/issues/2836/cefstreamreader-createforfile
• A work in progress list of CEF issues that are likely relevant to CefSharp is available at https://gist.github.com/amaitland/aec2d464e6dd75e5f0ff8fa8c9503b3a
• See https://github.com/cefsharp/CefSharp/issues?q=is%3Aissue+is%3Aopen+label%3Aknown-issue for other known issues

Breaking Changes

• For Network Service API changes see https://github.com/cefsharp/CefSharp/issues/2743
• IJavascriptObjectRepository.Register removed isAsync default param, you must now specify the third method param see #3016 for details and example
• CefSharp.WinForms.Internals.ControlExtensions.InvokeOnUiThreadIfRequired is now internal, it was never intended to be part of the public API #2983
• CefSettings.EnableNetSecurityExpiration and RequestContextSettings.EnableNetSecurityExpiration were removed #2954
• IFrame.LoadStringForUrl has been removed as CEF removed CefFrame::LoadString see #2955
• CefSharp.WebBrowserExtensions.RegisterJsObject/RegisterAsyncJsObject methods have been removed, you must now directly register your objects with the IJavascriptObjectRepository see #2990 for details and examples for migration.
• IAudioHandler has been removed as CEF now longer supports this feature #2918 (it's likely to be re-added at some point)
• IMethodInterceptor.Intercept now has the paramaters passed to allow for more advanced scenarios see #2909
• IBinder.Bind now has all arguments passed instead of just IDictionary/IList to allow for more flexible type conversion see #2908
• Javascript Binding methods are now executed on the ThreadPool instead of their own dedicated thread, see 2873

Bug Fix Release

This release addresses a CRITICAL SECURITY issue, everyone that uses CefSharp for internet browsing should upgrade. Those using for only intranet browsing the risk is obviously smaller, though you should perform your own risk analysis. I recommend that everyone upgrade.

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-5786
