есть вот такая ошибка
| Цитата |
"WhaBot_chrom.exe" (CLR v4.0.30319: WhaBot_chrom.exe). Загружено "C:\Windows\Microsoft.Net\assembly\GAC_MSIL\mscorlib.resources\v4.0_4.0.0.0_ru_b77a5c561934e089\mscorlib.resources.dll". Сборка модуля выполнена без символов.
Необработанное исключение: System.Exception: The ChromiumWebBrowser instance creates the underlying Chromium Embedded Framework (CEF) browser instance in an async fashion. The undelying CefBrowser instance is not yet initialized. Use the IsBrowserInitializedChanged event and check the IsBrowserInitialized property to determine when the browser has been initialized.
