New Windows Phone Mango Beta Build Released For Developers

It seems Mr Thurrott’s sources were wrong once again.  The Microsoft pundit predicted a new release to developers in a month’s time, but as per last time the Windows Phone Dev Podcast team appeared to have the more reliable sources.

Microsoft today announced the release of Windows Phone SDK 7.1 “Beta 2 Refresh”.  Here are the top 5 features Microsoft mentioned in their blog today,

  • Application platform APIs are now locked; you can feel confident to start getting ready for submitting your apps next month.
  • Emulator now has a nifty screenshot capability built in, allowing you quickly snap quality images of your app without the need of separate tools or cropping time. The images are great for use in app submission process or to share on your blog or with folks such as my team (hint hint).
  • The profiler has been greatly improved and provides memory profiling.
  • As of this drop, you can install NuGet into the free version of the WPSDK tools. I find NuGet to be one of my favorite productivity boosters and I’m happy to see the extension supported in the free tools.
  • The drop includes an initial peek at the Marketplace Test Kit; with the RC release, you’ll be able to use the included version of this toolkit to test your XAP file against the same certification testing tools that we use when ingesting apps for the Marketplace. For this refresh, it’s there but not fully functional; but more on this in a future blog post.

The update consists of a slightly updated Zune desktop client (to version 4.8.2134.0), build 7712 of Windows Phone 7, which is not the RTM version, but according to Cliff Simpkins close enough, and of course an updated toolkit and emulator.
