SDK makes it embed metro mapping code for apps
As expected with a beta release, not all functionality of the ultimate SDK will be available. It will support road views, aerial and bird's-eye imagery, as well as a traffic overlay. Some features initially will be available only to US-based developers. To encourage usage of the SDK, Microsoft is allowing free and unlimited use of Bing Maps controls and APIs within developers' Metro style apps during the time Windows 8 is available as a pre-release.
