Hello,
I have built service library using "generator-angular2-library" template and updated it with angular V "^4.4.6", then used it in andular-cli all working fine..
The library module looks like

export class ServiceLibraryModule { 
  static forRoot(config:any): ModuleWithProviders {
    return {
      ngModule: ServiceLibraryModule ,
      providers: [Serv1
        Serv2 
        { provide: MODULE_CONFIG, useValue: config }]
    };
  }
}

where export const MODULE_CONFIG = new InjectionToken<any>('');
to pass config parameters to the services of the library before using it.

now when I want to reuse my library in aspnetcore angular SPA project with V "^4.4.6", I added the "ServiceLibraryModule " to "app.shaed.module.ts" of the Angular-SPA project similar to what I did in angular-cli,

 imports: [...
ServiceLibraryModule .forRoot({"config_url" : "http://somedomain"}),
....]

but I keep getting the error:
"Uncaught Error: Can't resolve all parameters for Serv2 : ([object Object], ?)."

the Ser2 class looks like

export class Serv2
{

    constructor( private http: Http,@Inject(MODULE_CONFIG) private config:any){}
.....
}

can you help me find out what I did wrong or how to fix this issue in Angular-SPA, as the services library is working fine in angular-cli same version "^4.4.6".
