После того как я разработал расширение chrome, я хочу разработать свой первый Int enet Explorer 11 addon, я написал код, основанный на этом ответе. Когда я запускаю проект, похоже, что мне удалось создать надстройку:
В разделе «Настройки» -> «Управление надстройками» я вижу свою надстройку:
Но как мне показать сообщение "Hello world" (я только хочу проверить, действительно ли мое расширение работает, даже сообщение console.log)
Что я сделал:
- Я открыл проект библиотеки классов (. NET Framework 4.6.1)
- Добавил ссылку на
mshtml и SHDocVw и System.Windows.Forms (все встроенные не нужно загружать) - Добавлен класс
Interop и класс IEAddon. - Установить события сборки
- Установить аргументы Debug и запустить внешнюю программу
Здесь Мой код:
