У меня странная проблема с простым GET / POST, работающим в IE11 с Angular 6 - Symbol (rxSubscriber) не определен. Та же проблема возникла на Angular 5. К сожалению, обновление не помогло. Этот код хорошо работает в Chrome и Firefox, но в IE я получил ошибку, показанную ниже. Что еще интереснее, тот же код также хорошо работает, когда ng обслуживает и запускает IE11. Angular наследуется в представлении ASP .NET MVC, как показано ниже. Также полифиллы раскомментированы, как и должно быть для работы в IE. Приложение представляет собой комбинированный .NET WebForms / .NET MVC / Angular. Есть идеи, как это исправить?

Мой код выглядит так:
