.Net Core + Angular 2 : can't load module

Question

I am trying to implement Angular 2 with help of gulp in .Net Core using visual Studio update 3 with npm version 4.4.4 and node version v6.10.0 and already installed Typescript tool. All are

here is my Github link

And quick description of code

1.gulpfile.js

    /// <binding BeforeBuild='libs' Clean='clean' />

    var gulp = require('gulp');
    var rimraf = require('rimraf')
    var paths = {
        npm: './node_modules/',
        lib: './wwwroot/lib/'
    };
    var libs = [
       paths.npm + 'core-js/client/shim.min.js',
       paths.npm + 'zone.js/dist/zone.js',
       paths.npm + 'reflect-metadata/Reflect.js',
       paths.npm + 'systemjs/dist/system.src.js'
    ];
    gulp.task('libs', function () {
        return gulp.src(libs).pipe(gulp.dest(paths.lib));
    });
    gulp.task('clean', function (callback) {
        rimraf(paths.lib, callback);
    });

2. package.json

{
    "version": "1.0.0",
    "name": "asp.net",
  "private": true,
  "dependencies": {
    "@angular/common": "~2.4.0",
    "@angular/compiler": "~2.4.0",
    "@angular/core": "~2.4.0",
    "@angular/forms": "~2.4.0",
    "@angular/http": "~2.4.0",
    "@angular/platform-browser": "~2.4.0",
    "@angular/platform-browser-dynamic": "~2.4.0",
    "@angular/router": "~3.4.0",

    "angular-in-memory-web-api": "~0.2.1",
    "systemjs": "0.19.40",
    "core-js": "^2.4.1",
    "reflect-metadata": "^0.1.8",
    "rxjs": "5.0.1",
    "zone.js": "^0.7.4"
  },
  "devDependencies": {
    "gulp": "^3.9.1",
    "rimraf": "^2.6.1"
  }
}

3. tsconfig.json

{
  "compilerOptions": {
    "noImplicitAny": false,
    "noEmitOnError": true,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5",
    "module": "commonjs",
    "outDir": "wwwroot/app/",
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  },
  "exclude": [
    "node_modules",
    "wwwroot/lib",
    "wwwroot/app"
  ]
}

4. typings.json

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160725163759",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160909174046"
  }
}

first thing use of systemjs.config,js file is missing so add it and as per systemjs.config.js file change in gulpfile for required angular dependent files so here is a change

gulpfile.js /////

//var gulp = require('gulp');
//var rimraf = require('rimraf')
//var paths = {
//    npm: './node_modules/',
//    lib: './wwwroot/lib/'
//};
//var libs = [
//   paths.npm + 'core-js/client/shim.min.js',
//   paths.npm + 'zone.js/dist/zone.js',
//   paths.npm + 'reflect-metadata/Reflect.js',
//   paths.npm + 'systemjs/dist/system.src.js'
//];
//gulp.task('libs', function () {
//    return gulp.src(libs).pipe(gulp.dest(paths.lib));
//});
//gulp.task('clean', function (callback) {
//    rimraf(paths.lib, callback);
//});


var gulp = require('gulp');

var libs = './wwwroot/libs/';

gulp.task('default', function () {
    // place code for your default task here
});

gulp.task('restore:core-js', function () {
    gulp.src([
        'node_modules/core-js/client/*.js'
    ]).pipe(gulp.dest(libs + 'core-js'));
});
gulp.task('restore:zone.js', function () {
    gulp.src([
        'node_modules/zone.js/dist/*.js'
    ]).pipe(gulp.dest(libs + 'zone.js'));
});
gulp.task('restore:reflect-metadata', function () {
    gulp.src([
        'node_modules/reflect-metadata/reflect.js'
    ]).pipe(gulp.dest(libs + 'reflect-metadata'));
});
gulp.task('restore:systemjs', function () {
    gulp.src([
        'node_modules/systemjs/dist/*.js'
    ]).pipe(gulp.dest(libs + 'systemjs'));
});
gulp.task('restore:rxjs', function () {
    gulp.src([
        'node_modules/rxjs/**/*.js'
    ]).pipe(gulp.dest(libs + 'rxjs'));
});
gulp.task('restore:angular-in-memory-web-api', function () {
    gulp.src([
        'node_modules/angular-in-memory-web-api/**/*.js'
    ]).pipe(gulp.dest(libs + 'angular-in-memory-web-api'));
});

gulp.task('restore:angular', function () {
    gulp.src([
        'node_modules/@angular/**/*.js'
    ]).pipe(gulp.dest(libs + '@angular'));
});

gulp.task('restore:bootstrap', function () {
    gulp.src([
        'node_modules/bootstrap/dist/**/*.*'
    ]).pipe(gulp.dest(libs + 'bootstrap'));
});

gulp.task('restore', [
    'restore:core-js',
    'restore:zone.js',
    'restore:reflect-metadata',
    'restore:systemjs',
    'restore:rxjs',
    'restore:angular-in-memory-web-api',
    'restore:angular',
    'restore:bootstrap'
]);

index.html file under wwwroot folder

<html>
<head>
    <title>Angular QuickStart</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

and most important 3.systemjs.config.js file

    /**
     * System configuration for Angular samples
     * Adjust as necessary for your application needs.
     */
    (function (global) {
        System.config({
            paths: {
                // paths serve as alias
                'npm:': 'libs/'
            },
            // map tells the System loader where to look for things
            map: {
                // our app is within the app folder
                app: 'app',
                // angular bundles
                '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
                '@angular/common': 'npm:@angular/common/bundles/common.umd.js',

            },
            // packages tells the System loader how to load when no filename and/or no extension
            packages: {
                app: {
                    main: './main.js',
                    defaultExtension: 'js'
                },
                rxjs: {
                    defaultExtension: 'js'
                },
                'angular-in-memory-web-api': {
                    main: './index.js',
                    defaultExtension: 'js'
                }
            }
        });
    })(this);
