body: <p>I have an error</p>
  
  <pre><code>Can't bind to 'formGroup' since it isn't a known property of 'form'
  </code></pre>
  
  <p>after update project to angular2 RC.5</p>
  
  <p>app.module.ts:</p>
  
  <pre><code>@NgModule({
  declarations: [
      AppComponent
  ],
  imports: [
      BrowserModule,
      DeprecatedFormsModule,
      HttpModule,
      TranslateModule.forRoot({
        provide: TranslateLoader,
        useFactory: (http: Http) =&gt; new TranslateStaticLoader(http, '/assets/i18n', '.json'),
        deps: [Http]
      }),
      ConfigurationDevicesModule,
      ConfigurationEditModule,
      ControlModule,
      ResourceEditModule,
      UniWebControlInfoModule,
      routing
  ],
  bootstrap: [ AppComponent ]
  })
  
  export class AppModule {
  
  }
  </code></pre>
  
  <p>myComponent.module.ts </p>
  
  <pre><code>@NgModule({
  declarations: [
      ConfigurationDevicesComponent
  ],
  imports: [
      BrowserModule,
      TranslateModule
  ],
  exports: [
      ConfigurationDevicesComponent
  ]
  })
  
  export class ConfigurationDevicesModule {
  
  }
  </code></pre>
  
  <p>template html example:</p>
  
  <pre><code>&lt;form [formGroup]="selectBackground"&gt;
                          &lt;div *ngIf="backgrounds" class="form-group"&gt;
                              &lt;h5&gt;{{ 'CONFIGURATION_DEVICES.ALL_BACKGROUNDS' | translate }}&lt;/h5&gt;
                              &lt;select formControlName="selectBackgroundId"&gt;
                                  &lt;option *ngFor="let background of backgrounds" [value]="background.id"&gt;{{ 'CONFIGURATION_DEVICES.ID' | translate }} {{ background.id }} {{ 'CONFIGURATION_DEVICES.NAME' | translate }} {{ background.name }}&lt;/option&gt;    
                              &lt;/select&gt;
                          &lt;/div&gt;
                      &lt;/form&gt;
  </code></pre>
  
  <p>In angular 2 RC4, formGroup worked fine.</p>
  
  <p>I tried to import both DeprecatedFormsModule and DFormsModule , the problem is the same . In official documentation Angular now I can not find any mention about formGroup or again changed the way of building forms?</p>
