If you've ever tried to find a way to display an ESRI ShapeFile on a Virtual Earth map, you'll have probably noticed how little information there is on the Internet about how to accomplish this apparently arduous task. With the technique described in this article, you're going to be able to not only display Shapefiles as layers on Virtual Earth, but also interact with them in countless ways: extract data from them, show data associated with a shape when you click on it on the map, even modify or create new Shapefiles.

In this article we'll see how easy it is to use Virtual Earth SDK to produce a simple mashup, using web services that provide information in JSON format.

In this follow-up we'll build upon what we learned in the previous article, and write a simple AJAX application that calls a JSON Web Service asynchronously and displays the result with a callback. We'll leverage the ASP.NET AJAX client library to avoid writing all the needed "plumbing" code and we'll see how to bridge a remote web service using a local proxy.
