Notes

• CefSharp requires Visual C++ 2015. See #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, MP4 video is not.
• 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 #228 (comment) 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
• Save as PDF is not working when viewing PDF with Print Preview enabled see https://bitbucket.org/chromiumembedded/cef/issues/2867/save-as-pdf-is-not-working-in-pdf-viewer
• CanExecuteJavascriptInMainFrame incorrectly false after loading page with different origin #3021
• WPF Browser goes blank if used in combination with 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
• Print Preview only works in WinForms see #2332 (comment)
• LocalStorage not persisting to disk when using a relative CachePath (#3074) change to using an absolute path.

• IJavascriptObjectRepository.Register removed isAsync default param, you must now specify the third method param see #3016 for details and example

• IMethodInterceptor.Intercept now has the paramaters passed to allow for more advanced scenarios see #2909
