  Notes

  • 🚀 CefSharp requires Visual C++ 2015. See #1983 for details. You can bin deploy the VC++ dependencies, read the FAQ for more.
  • 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 #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.
  • 0️⃣ 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

  • 👀 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
