Angular 2 Component is not part of any NgModule

angularupgrade

i'm upgrading my Angular 2 project from RC5 to 2.0.0. I get this Error

Unhandled Promise rejection: Component LoginComponent is
not part of any NgModule or the module has not been imported into your
module. ; Zone: ; Task: Promise.then ; Value: Error: Component

Main.ts:

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

import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

AppModule:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { AppComponent }  from './app.component';
import {RouterModule} from "@angular/router";
import {AppsAdminComponent} from './AppsAdmin/AppsAdmin.component';
import {AppsManagerComponent} from './AppsManager/AppsManager.component';
import {LoginComponent} from './Login/Login.component';
import {LogoutComponent} from './Logout/logout.component';
import { Routing }  from './App.routing';
import {HttpModule} from '@angular/http';
//import {AppsManagerService} from './Service/AppsManager.service';
import {GlobalService} from './Service/GlobalService';
import {Webservice} from './Service/Webservice';

@NgModule({
    declarations: [
        AppComponent,
        LoginComponent,
        LogoutComponent,
        AppsAdminComponent,
        AppsManagerComponent
    ],
    imports: [
        BrowserModule,
        HttpModule,
        FormsModule,
        Routing
    ],
    providers: [
        GlobalService,
        Webservice

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

Login @Component:

@Component({
    selector: 'Login',
    templateUrl: 'App/Login/Login.html',
    providers: [LoginService],
    styleUrls: ['App/Login/Login.css']
})

What is wrong?

I had the same issue moving from RC5 to Final and it took me a bit to find my answer. I finally found my answer after remembering I was receiving warning messages "NgModule AppModule uses LoginComponent via "LoginComponent" but it was neither declared nor imported! This warning will become an error after final." When i finally looked about that error message I found my answer which might be similar to yours. I found my answer here.

What this post clued me in on was that in my app.module.ts file I had declared my components as the following:

app.module:

import { AccountComponent, AccountDetails } from './account/index'; import { LoginComponent, ResetPasswordComponent } from './login/index';

But in my routes file it was the following:

import { AccountComponent, AccountDetails } from './Account/Index'; import { LoginComponent, ResetPasswordComponent } from './Login/Index';

So the routes thinks its loading a different component then the module due to differences in the capitalization, which means the ones being pulled into the routes were not the same ones as the module.

Hope it might help.
