Bing Map in NAV 2013


I am trying to integrate Bing Map in NAV2013, using a blog on the following link:…/hand-on-addin-workshop-nav-2013-creating-a-bing-map-addin-with-server-side-geocoding.aspx

But seems some of the file on the link are missing and those are not NAV objects rather some .dll files.

Has anyone done this in NAV2013? If yes, could you please share how to do?
