CEFSHARP Cannot using cef.shutdown in Windows Form

Question

I run my cefsharp application using task scheduler on windows server. I have succeed exit with Application.exit(). But the status in task scheduler is still running not stopped.

I think, it was happenned because I didn't use Cef.shutdown(). But in this case I am getting error when use this syntax like this :

**`

Shutdown must be called on the same thread that Initialize was called - typically your UI thread. CefSharp was initialized on ManagedThreadId: 10

`**

Please help to solve this issue. Thanks

what is odd is I get that error when I DON'T call Cef.shutdown — Garr Godfrey, Mar 19 '18 at 01:30
@GarrGodfrey can you give me the details why that error happened ? — rizkidzulkarnain, Mar 21 '18 at 02:54
turned out the Application_Exit event was being posted prematurely. — Garr Godfrey, Mar 22 '18 at 03:48
idk. CefSharp adds an event handler for Application Exit and detects it wasn't shut down and throws that error. Seems it should happen in your case. — Garr Godfrey, Mar 23 '18 at 20:23
My guess is you are calling Cef.Initialize from a weird place, not the main UI thread. — Garr Godfrey, Mar 23 '18 at 20:24

I experienced this issue. As the error suggests it does relate to threading, in my example the browser existed on another form which was created on a second thread. A quick solution was to inject the ChromiumBrowser into the constructor of the second form, that way it was disposed correctly from the main thread.

Hope this helps someone!
