Error building sample app #470

I followed Steve Sanderson's very nice article "ASP.NET Core + Angular 2 template for Visual Studio". Everything seems OK, but when I try to run the project it complains and refuses to run (see stack trace below). So I'm filing an issue here as suggested in the article. Thanks!

An unhandled exception occurred while processing the request.

Exception: Call to Node module failed with error: Error: Zone.js has detected that ZoneAwarePromise (window|global).Promise has been overwritten.
Most likely cause is that a Promise polyfill has been loaded after Zone.js (Polyfilling Promise api is not necessary when zone.js is loaded. If you must load one, do so before loading zone.js.)
