CEF Crash During Application Close

[Greg]

Using CEF WinForms 75.1.141 in Windows Desktop Application on Windows:

Occasionally, when closing the application, the following is observed in the Windows Application Event Log:
Faulting module name: libcef.dll, version: 75.1.14.0, time stamp: 0x5d071e50
Exception code: 0x80000003
Fault offset: 0x00000000020a24bb

(Also, a dialog is shown that the application has "stopped working").

In know these can be very vague. Is there anything in general that should be done when closing an app, to ensure that the CefSharp is closed gracefully? Any other thoughts appreciated. Thank You

0x80000003 is STATUS_BREAKPOINT (or EXCEPTION_BREAKPOINT).
This means the execution is hitting a failed CHECK on close. Usually this is an unreleased object, libcef checks for a number of objects to have refcount zero on shutdown.

Without a crash dump and log, is hard to say which is it.
Try to run from a command prompt with --enable-logging --v=1 (or 2, 3 etc.) and make sure you have the corresponding libcef.dll.pdb (and perhaps others if needed) files near your libcef.dll. This normally displays a stack trace which may help i9n diagnosing which object or objects are not released.

It's most likely https://bitbucket.org/chromiumembedded/ ... closing-if you are seeing.

Try disabling the network service see https://github.com/cefsharp/CefSharp/is ... -521892919 for an example.
