My good friend and Virtual Earth guru, Marc Schweigert has just published a great two part video on how to build Virtual Earth v6.1 applications using JavaScript. Marc then goes into some details on how to leverage the ASP.NET AJAX and also Windows Communication Foundation (WCF). As a kicker he also shows how to build a VE application as a desktop application.

This is a great video to watch. Marc is an excellent presenter and has deep knowledge on Virtual Earth. If you were at Tech Ed North America this year and picked up a Virtual Earth Developer Resource Kit at my session or at our booth this year you already have this so definitely check it out.

Even better, Marc has posted the deck and the code for this presentation so definitely check it out.
