I downloaded the 4.2 beta 3 again. I had the problem of the "no response". Since then, I have a new pc running windows 7 64. I do not know if anything changed from the Oct time frame as far as download version. I started with Sam-ba and reinstalled everything. I was able to go into Visual Studios 2010 and with a copy of the program that I found here in the forums, I was able to write to a 2gb sd card. Yeh. Now for some almost good news. I was not able to write to a 8gb sd card. I installed 4.1.1 B1 and everything worked including reading and writing to the 8 gb sd card. The same card will not work in 4.2 b3. I went back and forth between the different beta releases and the results were consistent.
Once the community tells us that the .NET MF 4.2 firmware is stable, we'll make it an official release and post it on the Downloads page... Right now, there are some core bugs to work out still. [We're checking in some new bug fixes today to see how they affect stability.]

Not sure if windows xp was the difference or the speed of the machine that would not allow 4.2 b3 to work properly, unless there was a newer version that I downloaded from the first post from this thread.
I did have one problem with 4.1.1 b1 with the reading of the 8 gd card initially. Netduino+ was plugged into a usb hub that was plugged into a powered usb hub. That caused my machine to crash. I could not get Netduino to be recognized until I re powered the usb hub. I will try this setup with 4.2 once I can get 4.2 version to read a 8 gb sd card.
Thanks for all the hard work.
