Текущий SynchronizationContext нельзя использовать в качестве TaskScheduler. из CEFsharp EvaluateScriptAsync

Я пытаюсь асинхронно выполнить некоторый код JS в браузере CEF через CEFSharp. Мой код выглядит так;

debugForm = new CEFdebugger();
debugForm.browser.LoadingStateChanged += new EventHandler<CefSharp.LoadingStateChangedEventArgs>(webBrowser_LoadingStateChanged);
...
debugForm.browser.Load("local://wwwpub/index.html");
debugForm.Show();
...

void webBrowser_LoadingStateChanged(object sender, CefSharp.LoadingStateChangedEventArgs e)
{
    if (!e.IsLoading)
    {
            var task = debugForm.browser.EvaluateScriptAsync("1+1");
            task.ContinueWith(response =>
            {
...
            }, TaskScheduler.FromCurrentSynchronizationContext());
        }
    }

}

Линия;

task.ContinueWith(response =>

Проблема решилась заменой

task.ContinueWith(response =>
{
    ...
}, TaskScheduler.FromCurrentSynchronizationContext());

с этим

task.ContinueWith(response =>
{
    ...
});
