WP7 SDKがTechnical PreviewからBetaにあがりました。
First things first: go get the Windows Phone Developer Tools Beta. It has arrived!
The term “Beta” is understood to mean that things are close to being finished. Well, that’s what we mean anyway. This Beta release represents the near final version of the tools for building applications and games for Windows Phone 7.
Since the initial CTP release of the tools just this March, the Windows Phone Developer Tool CTP has been widely embraced by the community, and they have shown what’s possible on our new development platform.
It’s time to get serious about building the actual apps and games for Windows Phone 7 that consumers will be looking for starting this holiday season.
