'router-outlet' is not a known element

I have a mvc 5 project with a angular frontend . I wanted to add routing as described in this tutorial https://angular.io/guide/router. So in my _Layout.cshtml I added a




and created my routing in my app.module. But when I run this I get the following error:

Error: Template parse errors:
    'router-outlet' is not a known element:
    1. If 'router-outlet' is an Angular component, then verify that it is part       of this module.
    2. If 'router-outlet' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA'   to the '@NgModule.schemas' of this component to suppress this message. ("
    dashboard
    
    [ERROR ->]
     "): ng:///AppModule/AppComponent.html@5:0

In my app.component the line




gives an error telling me that Visual studio cannot resolve the tag 'router-outlet'. Any suggestions how I can fix this error? Am I missing a reference or a import or just overlooking something?

Below are my package.json ,app.component and app.module

package.json:

{
    "version": "1.0.0",
    "name": "app",
    "private": true,
    "scripts": {},
    "dependencies": {
    "@angular/common": "^4.2.2",
    "@angular/compiler": "^4.2.2",

    },

    "gulp-typescript": "^3.1.7",
    "path": "^0.12.7",
    "typescript": "^2.3.3"
    }
}

app.module.ts:

`import { NgModule } from '@angular

Try with:

@NgModule({
imports: [
BrowserModule,
RouterModule.forRoot(appRoutes),
FormsModule
],
declarations: [
AppComponent,
DashboardComponent
],
bootstrap: [AppComponent]
})
export class AppModule { }


There is no need to configure the exports in AppModule, because AppModule wont be imported by other modules in your application.
