I tried reflashing the firmware back to 4.2.2, and it worked (using VS2010 express).  Would rather have used the latest build, but I'll take what I can get.  If anyone knows where I went wrong with 4.3.1, please let me know.

Thanks for the quick reply. I've been clicking the Start button, but I just tried F5 instead.  Also tried pushing onboard reset button.  I've checked that the project is designated as the startup.

When I deploy, the blue LED comes on for a second while the program loads, and I don't see any error messages in VS.  Is there anything else I can try?

This may have been answered elsewhere but I haven't found it.  I have:

Netduino plus 2

4.3.1 firmware

Win 7

VS 2012

I can deploy the Blinky program, but the onboard LED never blinks.  I know the blue LED is ok because it lights up when I deploy. I have reflashed the drive 3x, I've checked the references and they are all 4.3.1.  What else can I try?

                // blink every 1 second
                led.Write(true);        // turns the LED on
                Thread.Sleep(1000);     // waits 1 second
                led.Write(false);       // turns the LED off
                Thread.Sleep(1000);     // waits 1 second
            }

I am not able to update the firmware on my NDP2 to 4.3.1.0 (it's curently 4.2.0.0).  I am using VS2012.  I've gone through the setps in your article - I did try updating the driver to the one from DfuSe_Demo_V3.0.3_Setup_amd64, but the msg is "the best driver for your device has already been installed".  The Netduino Update 4.3.1.0 just doesn't see it (window is empty).  And yes, I did put the board into boot loader mode.  Any help appreciated.

I also have VS2008.  Will that work with firmware4.2.0.0?
