Though the `@NgModule` decorator has an `entryComponents` array, most of the time
you won't have to explicitly set any entry components because Angular adds components listed in `@NgModule.bootstrap` and those in route definitions to entry components automatically. Though these two mechanisms account for most entry components, if your app happens to bootstrap or dynamically load a component by type imperatively,
you must add it to `entryComponents` explicitly.
