    To fix that, you have 2 options: A. in main.ts:

    import {FORM_PROVIDERS} from 'angular2/common';
    
    // other code here
    
    bootstrap(AppCmp, [
      ROUTER_PROVIDERS,
      provide(LocationStrategy, { useClass: HashLocationStrategy }),
      FORM_PROVIDERS
    ]);
    

    B. in your component that uses the form:

    import {FORM_PROVIDERS, FORM_DIRECTIVES} from 'angular2/common';
    @Component({
      providers: [FORM_PROVIDERS],
      directives: [FORM_DIRECTIVES]
    })
