WP7の開発環境が先週更新されたらしく、Marketplace Nersletterに新しくなったので更新してね！との旨書かれていました。
- A new Bing Maps Control that improves map performance during user gestures
- The Capability Detection Tool, which scans your application and reports on detected phone capabilities that will be applied during ingestion to marketplace.
- The WP Connect Tool, with which you can create a connection between the Windows Phone and your PC without requiring Zune to be running, so you can debug media APIs.
この3つが主な変更なようですね。
