Chris,
I do not really know what I am doing - but I am persistent ...
Laptop.
I (re) installed micro framework V4.1 and this allowed C# to load and build my app.
I downloaded the Netduino Firmware 4.2 and after many attempts finally managed to install EF_Flash and EF_config.
Device manager can now see the Netduino as a USB device with driver 6.1.7601.17514.
VS2010 however cannot deploy my app - "an error has occurred please check your hardware".
Progress but the need for MicroFrameWork to be installed is a bit worrying! And it still does not run my app.
-------------------------
On my OSX (w8.1pro) the first time I tried to deploy and debug my app on the newly set up Netduino it all worked as expected!!!! My app ran just fine.
BUT when I stopped the debug and rebuilt/redeployed my app it ran into the " ... not initialised state; rebooting". (disconnected the Netduino and tried again - no change) shutdown parallels etc and reloaded everything - no change. So it ran once and that was it!
Thank-you for your patience and support
David
