Have walked through the setup steps on a new computer, running Win10, VS2015, and a new N3 Wifi.
Installed the following in order:
netmfvs 14 dot net
I was able to run zadig and update the firmware on the N3 to WinUSB(v6.1). At this point the blue and white lights are on.
Loaded Blinky in VS
changed Properties so that I am running .Net4.3 and changed .Net Micro Framework from Emulator to USB but I cannot see any devices. Blinky errors out cause it cannot talk to the Netduino.
Went back to Programs and Features:
Confirmed that .net Micro Framework SDK 4.3 was installed
Confirmed that Netduino SDK v4.3.2 was installed
Went back to Device Settings:
STM32 BootLoader is installed under Universal Serial Bus devices -- odd?
STM32 showed an error " STM32 bootloader was not migrated.
Removed STM32 device and driver
