Despite being listed in the entry components, HelloComponent is not actually included in the NgModule

Check out my StackBlitz demo where I am experimenting with dynamically instantiating the HelloComponent using the ReflexiveInjector. The HelloComponent is added to the app modules entryComponents array.

Despite this setup, I am still encountering the following error:

Component HelloComponent is not part of any NgModule or the module has not been imported into your module.

Any ideas on how to resolve this issue?

I have included a link to this Stack Overflow post in a feature request on GitHub proposing virtual / logical modules. Please support it by giving it a thumbs up if you find the suggestion useful.

Don't forget to add the HelloComponent to your module's declarations array. For more information, check out the official documentation on entry components.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

@NgModule({
  imports:      [ BrowserModule, FormsModule ],
  entryComponents: [HelloComponent],
  declarations: [ AppComponent, HelloComponent ], // make sure to declare here
  bootstrap:    [ AppComponent ]
})
export class AppModule { }
