Some gave short shrift to Windows Phone App Studio beta when it launched in August, but its web based development tool is proving to be popular -- developers have already built 65,000 apps. Microsoft hopes to keep that momentum going with a slew of App Studio upgrades that should make these fast-track apps even more powerful. Beta users can now integrate other phone functions into their apps with simple, menu-driven "actions" that include context-aware tasks like dialing numbers. The update also enables NFC for beaming software to other App Studio users, and it's possible to earn money through the official Windows Phone ad kit. Those keen on using any of the beta's new tricks just have to sign into App Studio at the source link.
