In my Angular2 app am getting the following error Error: (SystemJS) Unexpected value 'ReleasesService' declared by the module 'AppModule'. Please add a @Pipe/@Directive/@Component annotation.

My AppModule:

import { NgModule } from '@angular/core';

import { BrowserModule } from '@angular/platform-browser';

import { routing } from './app.routes';

import { HttpModule } from '@angular/http';

import { SearchFilter } from '../app/search-filter.pipe';

import { ReleasesService } from '../app/releases/releases.service';

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

import { HomeComponent } from '../app/home/home.component';

import { ReleasesComponent } from '../app/releases/releases.component';

import { DistroComponent } from '../app/distro/distro.component';

import { ContactComponent } from '../app/contact/contact.component';



@NgModule({

  imports:      [ BrowserModule, HttpModule, routing ],

  declarations: [ AppComponent, 

                  SearchFilter,

                  HomeComponent, 

                  ReleasesComponent, 

                  ReleasesService,

                  DistroComponent, 

                  ContactComponent  ],

  bootstrap:    [ AppComponent ]

})

export class AppModule { }

My ReleasesService:

import { Injectable } from '@angular/core';

import { Http, Response } from '@angular/http';

import { Observable } from 'rxjs/Observable';

import { IRelease } from './release';

import 'rxjs/add/operator/map';



@Injectable()

export class ReleasesService {

  getReleases() {

    return IRelease;

  }

}

How to fix it? I reinstalled the Quickstarter (the base for my App), and having the same error when try to create the service.
