Estoy convirtiendo el código React a mecanografiado, el objetivo en tsconfig es es5.

al ejecutarse en IE 11 aparece el error "La promesa no está definida"

Sé que necesito polyfill, pero ¿cómo?

No estoy usando Babel.

El siguiente es mi Webpack.config

var webpack = require("webpack");
var Promise = require('es6-promise').Promise;
var paths = require('./config/paths');
var HtmlWebpackPlugin = require('html-webpack-plugin');
//var InterpolateHtmlPlugin = require('react-dev-utils/InterpolateHtmlPlugin');
var AureliaWebpackPlugin = require('aurelia-webpack-plugin');

var publicPath = '/';
var publicUrl = '';

module.exports = {
    entry: {

    app: [
    'core-js/fn/promise',

    './Generated Files/app.js'
],
    vendor: paths.vendorPath,
},
output: {
    path:__dirname + "/dist",
    filename: 'bundle.js',
    publicPath: publicPath
},
devtool: '#source-map',
resolve: {
    extensions: ['', '.webpack.js', '.web.js', '.ts', '.tsx', '.js']
},
module: {
    loaders: [
      {
          test: /.tsx?$/,
          loader: 'ts-loader',
          exclude: /node_modules/
      },
      {
          test: /\.css$/,
          loader: 'style-loader!css-loader',
          //exclude: /node_modules/,
      },
      {
          test: /\.(ico|jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2)(\?.*)?$/,
          loader: 'file',
          query: {
              name: 'static/media/[name].[hash:8].[ext]'
          }
      },
    ]
},
plugins: [
  new webpack.HotModuleReplacementPlugin(),
  new webpack.DefinePlugin({
      'process.env': {
          'NODE_ENV': JSON.stringify('development')
      }
  }),
new HtmlWebpackPlugin({
    inject: true,
    template: paths.appHtml,
}),

// For using jQuery
     new webpack.ProvidePlugin({
     $: "jquery",
     jQuery: "jquery",
     'window.jQuery': 'jquery',
     'window.: 'jquery',
 }),

new webpack.ProvidePlugin({
   "Promise": "promise-polyfill"
}),
  // new AureliaWebpackPlugin(),
    new webpack.optimize.CommonsChunkPlugin({/* chunkName= */name:"vendor", /* filename= */filename:'static/js/vendor.js'})
    ]
    };
