Windows 10 IoT Core for Raspberry Pi 2
When they released this a couple of months ago I was pretty excited to try it out. I think the barrier to installation is a bit high.  First install Windows 10, then custom install of VS, install IoT Templates, then about 30 more steps before you get the image to flash on your SD.  How about a link to the image I can blast on the SD and kick the tires without a couple hours of downloading and installing prerequisites?
