Can't use component in Angular 8

I'm learning Angular 8 and even after searching for an hour on other questions I couldn't solve this. The solution seems to be under my nose but I can't see it. I keep getting this error:

'app-green' is not a known element: 1. If 'app-green' is an Angular component, then verify that it is part of this module. 2. If 'app-green' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

This is my app.module.ts code 

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

import { AppComponent } from './app.component';
import { ServerComponent } from './servers/server.component';
import { SubServerComponent } from './sub-server/sub-server.component';
import { GreenComponent } from './green/green.component';



@NgModule({
  declarations: [
    AppComponent,
    ServerComponent,
    SubServerComponent,
    GreenComponent,


  ],
  imports: [
    BrowserModule, 
    FormsModule, 

  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

and this is the component code: 

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-green',
  templateUrl: './green.component.html',
  styleUrls: ['./green.component.css']
})
export class GreenComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}

Any help will be appreciated.

You must also import the GreenComponent in the AppComponent, what you abviously didn't. It is not sufficient to import the GreenComponent in the AppModule as one could believe.

import { Component } from '@angular/core';
import { GreenComponent } from './green/green.component';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ],  

})
export class AppComponent  {
  ...
}
