Rider + ASP.Net Core + Kestrel

Im trying to create my first .NET Core app.

Dispite lots of searching...

http://benfoster.io/blog/how-to-configure-kestrel-urls-in-aspnet-core-rc2

And this link being the closest I can get to understanding...

How using Rider can I create a web app that runs in kestrel?

Any links for a walk through or test app which has all of the component parts would be very much appreciated.

Cheers,

Tom
