6 years ago How do I investigate my issue further?
It's important to remember that CefSharp is just a wrapper around the Chromium Embedded Project (CEF), the upstream CEF forum is a valuable resource. Also CEF has it's own Issue Tracker. Please take the time to research your own problem, including Googling, searching on ceforum, etc.

Finding more info
- Have you checked the
Debug.logfile? (Should be located in your apps executing folder by default) - Have you googled the error message your seeing? (Don't just google the whole thing, try googling just the keywords and possibly add
chromiumas a keyword). - Are you able to reproduce the problem using
cefclient? (cefclientis the reference implementation provided byCEF) - Need more help debugging? Check the Troubleshooting Guide
- Are you using the latest version? Check the Release Branches table to determine if the version your using is supported.

How do I download cefclient?
- Firstly identity which version of
CEFyour actually using, easiest way is to check yourpackages.configfile, look for thecef.redist.x86package, it's version will be something like3.2526.1362, that's the exact version ofCEFyou'll need to download for comparison. You can also openchrome://versionin the browser to determine the version. - Open http://opensource.spotify.com/cefbuilds/index.html in a web browser
- Locate the exact
Branchyou require, for the example above the branch is2526, all the versions follow a similar pattern - Locate the
Windows 32bitorWindows 64bititem, if you don't see the exact version, then clickmore revisions - Download Test App
- Are you using
WPF/OffscreenorWinForms?
This next part is key
- To compare with WPF/OffScreen run
cefclient --multi-threaded-message-loop --off-screen-rendering-enabled - To compare with WinForms
cefclient --multi-threaded-message-loop
What version of the product are you using? 63.0.3 via NuGet.
What architecture x86 or x64? x86 platform in build configuration.
On what operating system? Windows 10

What steps will reproduce the problem? Go to https://developer.microsoft.com/en-us/microsoft-edge/testdrive/demos/speechsynthesis/
The dropdown list of voices is empty! Supposed to be full.
Or, open a remote dev console for cefSharp project, and type window.speechSynthesis.getVoices(). The array is empty! Supposed to be an array of 20 SpeechSynthesisVoice objects.
What is the expected output? What do you see instead? Suppose to have at least 20 SpeechSynthesisVoice objects in an array, mine is empty. No crash
The browser is suppose to support Speech Synthesis
