This is because the upload only works currently with the STLink probe, not DFU like you tried.
At least I don't know about any DFU bootloader for F4 family which is working on windows, but I may be wrong.

Arduino IDE should actually upload only by STlink, don't know why it tried to upload over DFU...

EDIT
I know why, because it is set this way in boards.txt.
And I don't know how the Netduino creators planned the upload method, but according to the getting started document it should use USB.
You could try to push the RESET button when Arduino is displaying the uploading message.

@Martin, were you able to upload successfully to Netduino board over DFU?

During those past years, my Netduino2Plus was uploaded all the time with DFU with BOOT0 button, I've never used STLink with it since the connection is only available with pogo-pins.

So you have to press BOOT0 button and reset to come into bootloader mode, right? Then DFU upload should work.

Right ! This is the behaviour of F4xx internal bootloader.
