yes it should, as dfu device (or netduino in dfu mode or something like that) when you plug it in while the button pressed.
maybe try reinstalling netduino sdk fpr the drivers. if that doesent help, sry, iam out of ideas

first: the socket code/drivers is from an external nsource, lwip i think, so its not microsoft based
than: i had the same problem with my arduino, also cosm.
i fixed it that way:
i just restart the device every 10 minutes -.- (with software, later iam gonna add an attiny85 as external "watchdog" todo that)
since than i had no more problems.

joopc: no iam not kidding. i offered a solution (or workaround or whatever you want to call it)
gebrander: your 1.) i dont even try to answer, whatever man ...
2.) yes a workaround, cos it will take time to fix the real issue (wich has todo with the dhcp i assume)
if your lucky it will be fixed with the .netmf 4.3 version (new lwip version) -
if that isent the case, it will take a long time to get this fix, so what todo?
cry? or try to "fix" or workaround it yourself?
you can also do something usefull and support .netmf / lwip with better code
keep in mind that sl is not a billion dollar company with hundreds of developers, and there is many stuff that needs fixes/attention
also - if you change too much on the core, it gives troubles on the further netmf updates.

-.- i never said that i dont want it all fixed or something like that. i like working stuff
but the stupid answers about me kidding and that tv stuff indeed make me angry, i mean, i tried to offer
some help and my experience. iam in no way affiliated with sl or some company.
//edit: if id know a better solution (for now) id tell it.

i2c does not have/need a cs (chipselect) pin. it access the device with an address.
maybe the pin is used for something else.

i dont _think_ netmf supports this, but since its very basic stuff its easy to write your own (or just work directly with sockets)
btw: netmf doesent support async in sockets

i suggest not using a linear regulator for a car battery (you sure its 12v and not 24v ?)
linear regulators are inefficient and make a lot of heat, while swichting regulators are way more effiecent and
dont need cooling (at least for around 10 watts)
the cheap lm2577 regulators from ebay work great for that.
there are also some for more power (but 10 watts is a lot!! thats 2amp @ 5 volt)
//edit 2577 is step up, sry, i meant LM2596

Netduino Plus 2 (and Netduino Plus 1)
seriously thats a very complex watchdog i think.
iam using a attiny85 for that, and its just a few lines of code.
and for the netduino side its just setting a pin low and high.
there might be even simpler solutions (real watchdog ic's) - wich only needs to pull a pin low and high.

its not a bad idea, but you have to be carefull.
last few days 2 duinos got fried of beein not carefully enough with 12v.
i suggest opto-isolating the pins from netduino to the 12v stuff, not just a transistor/mosfet.

i like that usb power supply thingy, its what i suggested, a swichting regulator from ebay (LM2596) - yeah in the post before i mentioned the wrong one, i corrected this.
i use them a lot. 
about noise: well that depends: when i use a cheap cellphone charger i get a lot of noise, but
from a battery or a regulated power supply i get no noise at all (with the voltage first stepped up, than stepped down again, so 2x switching)
about the design: i think the chinese use the standard design from the datasheet.
there are also some versions that have current limiters, with them you can even charge li-** akkus.
its also kind of protection, so no fuse is needed.
(well, i just have the normal ones, when i short them they die, when i use more current than they can supply they drop the voltage a lot)

how did you get this values? doesent sound right to me.
was running code with a loop on all devices?
(my mini consumes ~30ma with fresh firmware install w/o program, but ~100-120ma with some code running)

if you use the ms analog class just read - returns a single from 0-1 .. where 0 = 0% and 1 = 100%
multiply it with 3.3 and you have the voltage.
like its value is 0.5 = 50% = 1.65v

btw: if you really _have to_ use the sl class (or used readRaw on ms class) the correct formula is:
Single voltage= sensorValue * (3.3f / 1024f);

what you are trying todo?
Utility.SetLocalTime(DateTime.Now); (example..) // working for me
the pwmchannels enum is a define from secretlabs, not microsoft. it just routes the pwmchannels to the right cpu.pwmchannel (thats from ms)
yes n+ supports 4.2. 4.2 is great!
for the webservice: sry no idea

the nRF24L01+ work very well, iam using them. on codeplex is a library for that device.
communication arduino <> netduino via the nrf i didnt got to work - i think its of the codebase, so its hard to find
out the right channel and addresses for each. theoretically it would work.
the 433 i suggest not to use, thats illegal in many countries, and there is also a lot of noise, and afaik
you have to filter the noise out yourself, while the nrf makes this for you.

it should work.
i have some suggestions: first: your setting the freq and duty in the constructor, so the led.Frequency and duty after that is not needed, set the values you want there. (and ofc wherever you wanna change it)
also, try setting tghe invert parameter to true, maybe helps (depends on the circiut wich you connected the led)
and try:
Single test = 0.0f;
while (true)
{
led1.DutyCycle = test;
test+= 0.05f;
if(test > 1.0f)
{
test = 0.0f;
}
Thread.Sleep(100);
}

what did you do before it stopped working?
i dont believe that a working duino stops working w/o you doing something.
that will help narrow down the error (call me pessimistic, but not getting recognized sounds very bad)

for testing and such i suggest using a thread.sleep(5*1000); at the beginning _before_ your code, so when you reset it it gives you enough time
to just remove the app or deploy a new one before it crashes again.
(and seriously, 5 seconds is not really that long ...)

you nearly got it 
its: //PWM backlightPwm0 = new PWM(PWMChannels.PWM_PIN_D3, 1000, 0.6f, false);
you cant use too low frequenzy (iam not sure whats the smallest value is you can use, theres a thread about it, gutworks explained it there)
first value is the pin, second is the freuqenzy in hz, thrid is the duty cycle in percent, 4th is the inverting setting (like 0.1f duty gets to 0.9f than -
thats just that you can use the same code for different external circiuts, cos it makes a difference wich transistor and such you choose, npn, pnp)
