body: <p>I was going thorugh the angular2.0 demo app but it seems that injectables are not working from build 24 and giving me error as <br/> "ORIGINAL ERROR: Cannot resolve all parameters for MyAppComponent. Make sure they all have valid type or annotations." <br/> till build 23 its working fine ,please help me with the issue <br/>
  below is the demo code, i had made few manipulations from the original just for learning purpose</p>
  
  <pre><code>import {Component, View, bootstrap, NgFor} from 'angular2/angular2';
  
  
  module foo{
    class FriendsService {
      names: Array&lt;string&gt;;
      constructor() {
          this.names = ["Alice", "Aarav", "Martín", "Shannon", "Ariana","Kai"];
      }
  }
  
  
  @Component({
      selector: 'array',
      injecetables: [FriendsService]
  
  })
  @View({
          template: '&lt;p&gt;My name: {{ myName }}&lt;/p&gt;&lt;p&gt;Friends:&lt;/p&gt;&lt;ul&gt;&lt;li *ng-for="#name of names"&gt;{{ name }}&lt;/li&gt;&lt;/ul&gt;',
          directives: [NgFor]
  }) 
     export class arrayComponent {
      myName: string;
      names: Array&lt;string&gt;;
  
      constructor(friendsService: FriendsService) {
         this.myName = 'Alice';
         this.names = friendsService.names;
       }
     }
   }
  
  bootstrap(foo.arrayComponent);
