Edit: this is not longer available, use this official release instead http://www.ghielectronics.com/community/forum/topic?id=11849
Please do not twitter, blog or link to this SDK yet. We will have an official announcement on Monday once the community approve it.
IMPORTANT: This SDK includes the latest gadgeteer SDK that supports VS2012 desktop. In order for you to use it, you need NETMF 4.3 SDK (but the firmware is still 4.2). You must uninstall everything NETMF and GHI related and then start with installing NETMF 4.3 found at http://netmf.codeplex.com/downloads/get/500745 then install the GHI package below.
IMPORTANT: Windows8 will not let you install till you click “more info” and then click “Run Anyway” button. See attached images please.
Tip: If you want to continue to use VS2010, keep using NETMF 4.2 QFE2 like before. This will not work in future once we switch to NETMF 4.3 and we no longer support VS2010 but it is up to you what to use. You can ignore the notes about needing Microsoft’s 4.3 SDK, but you are on your own. GHI only supports VS2012 to keep things simple and uniform and this is required in coming releases anyways…

Fixes/Additions and known issues: Please see release notes. We will summary in official announcement.
If you have issues with this package, reply to this post please to keep things contained to this particular release.
Edit: As suggested by many users, VS2012 will only work on Win7 and Win8 so we will continue supporting VS2010 for some time.
