Bing Maps Developer Resources: Map SDKs, APIs, Tips, Training
Bing Maps gives you a rich set of tools to help you create amazing map experiences. Choose from our super fast AJAX Control 7.0, our REST Services API, our Bing Map App SDK for mash-ups hosted on Bing.com/maps , and our Windows Phone 7 SDK to find the solution that is right for you. One of the best things about building on the Bing Maps Platform is the wide range of API choices. The AJAX Control 7.0 was built from the ground up to be smaller and faster.
