I have angular2 working with Visual Studio 2015. I had to install .NET 5 RC1 to support tsconfig.json. They have a completely new project structure which I like very much. Here is my setup:

You'll notice that I put my app folder and ts files inside my wwwroot - that's just my preference, and it's following the angular2 quickstart. I copied the bundled files from my node modules into my scripts folder inside my wwwroot.

I created a package.json based on the angular2 beta quickstart:

{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "license": "ISC",
  "dependencies": {
    "angular2": "2.0.0-beta.0",
    "systemjs": "0.19.6",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.0",
    "zone.js": "0.5.10"
  }
}

Then I right-clicked on the package.json and selected "Restore Packages" and it ran the NPM install to create the node_modules folder with all the packages you see. Then I setup my tsconfig.json like so and put it in the root:

{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules"
  ]
}

This is key to making it work. I actually had to reload the solution for it to see the tsconfig.json and start using it. In addition to this, I went into my Tools > Options and set the typescript options like so:

Next I added my index.html file:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>Sample Angular 2 App</title>
</head>
<body>
    <my-app>Loading...</my-app>

    <script src="scripts/angular2-polyfills.js"></script>
    <script src="scripts/system.src.js"></script>
    <script src="scripts/Rx.js"></script>
    <script src="scripts/angular2.dev.js"></script>
    <script>
        System.config({
            packages: {
                app: {
                    format: 'register',
                    defaultExtension: 'js'
                }
            }
        });

        System.import('app/boot').then(null, console.error.bind(console));
    </script>
</body>
</html>

The order of your script includes is important! Here's my MyApp.ts file:

import { Component } from "angular2/core";

@Component({
    selector: "my-app",
    template: `
        <div>Hello from Angular 2</div>
    `
})
export class MyApp {
    public constructor() {
    }
}

and my boot.ts file:

import { bootstrap } from "angular2/platform/browser";
import { MyApp } from "./MyApp";

bootstrap(MyApp);

At this point I felt I was ready to run it, so I launched it and navigated to my /index.html - but all I saw was "Hello World!". It seemed to be ignoring my path to serve index.html and was statically writing out text. Looking at the Startup.cs, I found the problem.:

namespace Angular2Demo
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app)
        {
            app.UseIISPlatformHandler();

            // Add this!
            app.UseStaticFiles();

            // Remove this!
            //app.Run(async (context) =>
            //{
            //    await context.Response.WriteAsync("Hello World!");
            //});
        }

        // Entry point for the application.
        public static void Main(string[] args) => WebApplication.Run<Startup>(args);
    }
}

By commenting out the app.Run and adding the app.UseStaticFiles(); (which required installing an additional package), I was ready to try again:

Success!
