Angular 2没有服务提供商

我正在尝试学习Angular 2和C#web api Core,并从这个视频开始.
https://channel9.msdn.com/Events/Visual-Studio/Visual-Studio-2017-Launch/WEB-103
他没有包含下载代码.我使用VS2017和脚手架工具创建了一个略有不同的文件结构.
我收到错误“异常：调用节点模块失败,错误：错误：未捕获(在承诺中)：错误：没有ServiceModuleService的提供程序！
错误：没有ServiceModuleService的提供程序！“
这是一些代码,请询问您是否需要了解更多信息.

app.module.shared.ts：

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { AppComponent } from './components/app/app.component'
import { ServiceModuleListComponent } from './components/service-module-list/service-module-list.component';
import { HeaderComponent } from './components/shared/header/header.component';
import { ServiceModuleService } from './components/shared/service-module.service';
import { ServiceModuleComponent } from './components/service-module/service-module.component';

export const sharedConfig: NgModule = {
    bootstrap: [AppComponent],declarations: [
        AppComponent,ServiceModuleListComponent,HeaderComponent,ServiceModuleComponent
    ],imports: [
        RouterModule.forRoot([
            { path: '',redirectTo: 'servicemodulelist',pathMatch: 'full' },{ path: 'servicemodulelist',component: ServiceModuleListComponent },{ path: '**',redirectTo: 'servicemodulelist' }
        ])
    ],providers: [ServiceModuleService]
};

app.module.client.ts：

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { sharedConfig } from './app.module.shared';

@NgModule({
    bootstrap: sharedConfig.bootstrap,declarations: sharedConfig.declarations,imports: [
        BrowserModule,FormsModule,HttpModule,...sharedConfig.imports
    ],providers: [
        { provide: 'ORIGIN_URL',useValue: location.origin },sharedConfig.providers
    ]
})
export class AppModule {
}

app.component.ts

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

@Component({
    selector: 'app',templateUrl: './app.component.html',styleUrls: ['./app.component.css']
})
export class AppComponent {
}

服务module.component.ts：

import { Component,Input } from '@angular/core';
import { ServiceModule } from '../shared/service-module.type';

@Component({
    selector: 'service-module',templateUrl: './service-module.component.html'
})
export class ServiceModuleComponent {
    @Input() serviceModule: ServiceModule

    constructor() {

    }
}

服务模块list.component.ts：

import { Component,OnInit } from '@angular/core';
import { ServiceModule } from '../shared/service-module.type';
import { ServiceModuleService } from '../shared/service-module.service';
import { ServiceModuleComponent }from '../service-module/service-module.component';

@Component({
    selector: 'service-module-list',templateUrl: './service-module-list.component.html'
})
export class ServiceModuleListComponent implements OnInit {
    serviceModules: ServiceModule[];

    constructor(private serviceModuleService: ServiceModuleService) {
    }

    ngOnInit() {
        this.serviceModuleService.getServiceModuleItems()
            .then(serviceModuleItems => {
                this.serviceModules = serviceModuleItems;
            });
    }
}

服务module.service.ts：

import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/Rx';
import { ServiceModule } from './service-module.type';

@Injectable()
export class ServiceModuleService {
    constructor(private http: Http) { }

    getServiceModuleItems() {
        return this.http.get('api/ServiceModuleItems')
            .map(response => response.json() as ServiceModule[])
            .toPromise();
    }
}

服务module.type.ts：

export class ServiceModule {
    idx: number;
    applicationName: string;
    isActive: boolean;
    description: string;
}

基本上在这一点上,在启动时,应用程序必须显示我在SQL表上的条目列表,并且服务调用api来获取它,但现在我遇到了这个问题并出现错误消息.
