Yesterday, the Windows Phone team released a refresh of the Windows Phone SDK 7.1 to registered developers. The refresh consists of two parts: the release of an updated Windows Phone SDK 7.1 and the Mango OS (Build 7712). Now is the time to install the updated tools and upgrade your phone.
- Install the tools: as a registered developer to App Hub you should have received an activation code to Microsoft Connect. Check out the list of resources for Mango developers here.
- Upgrade the phone: the process to update your phone with build 7712 is pretty straight-forward if you follow the steps. Note this build is not a RTM build – it’s still a pre-release build.
Follow the steps defined in the download manual, reading the details will save you running into issues so don’t skip that part.
Some of the new tooling features include profiler improvements, emulator screenshot feature, support for installing NuGet with the free Windows Phone SDK tools.
