Not FAT file access count - in a previous thread (that I can't now find) relating to out of memory issues you'd said you were going to reduce both the number and size of buffers allocated by the FAT file system. You also said in that thread you were going to change the wording of the GC message "Failed to allocate..." to clarify that it was a compaction trigger rather than an out of memory situation. The old wording remains so I wondered if the memory tuning got done and whether all this is in 4.2.We build the tuning down of buffer sizes into the v4.1.0.0 firmware, and it's now included in the v4.2 firmware as well.
What is the FAT file access count memory issue? If that has been changed in the 4.2 codebase, it's included as well.
The GC bugfixes are included for sure.
We'll be posting v4.2 beta 2 later this weekend, now with "WithEvents" support for VB programmers.

Thanks for clearsing this up.

I had it happen a couple times yesterday after going to 4.2 as well.
I just spotted that this issue despite a high vote count was closed on Codeplex this Monday by "lorenzte" with no explanation. Outrageous.
Seriously considering an alternative platform for my product development as NETMF is proving too painful and unproductive at the moment. I had high hopes for it.

I agree, but I'm not an expert of things and like we say in Dutch: "van 't kastje naar de muur". Litteraly: "from the cupboard to the wall" but loosly translated being bounced around.
So perhaps you could reply on that issue, or take some other actions? If you need me to test anything, you know how to contact me
The hang on deployment and the following BSOD on disconnect or reset is driving me crazy; makes serious development an absolute pain. It's happening to me on about 50% of deployments. Is there any known workaround? Is the 4.1 driver better than the 4.2? Is it happening only to a few people or everybody? Only 4 votes on codeplex. I'm using Win7 64bit and VS2010 Pro.

By the way, remember, beta software can always contain a few flaws, it's a risk using Beta firmware.
appairently you found a flaw
yup - trying to help find them and fix them!
#17409 Beta driver for .NET MF 4.2 RC3+

P.S. Does anyone have a simple project (something along the lines of "Hello world" or maybe a little more sophisticated) which regularly causes a BSOD?
Chris
My experience is that the problem is strongly exacerbated by the size of the project. I've a project that has a deployment size of 57k and it'll cause the BSOD on the second deployment; every time. I'm on Win7 x64 and Netduino Plus. So to get something reproducible just write "Hello World" and link in a buch of extra libraries.
The debug stack trace I posted pretty clearly shows a recusive behaviour around the operation completion continuation function. I also see that there's a check in of the driver code for RC2 that may be an attempt to fix this by putting a monitor on the completion.

Are you sending large amounts of debug info from the device by any chance?
It'd be nice to be able to get to the point where I could look at the debug info ;->
But no, with that project size the steps are:
Boot windows
Start VS
Deploy project
Click stop debug
Deploy project
Deploy hangs
Reset NP -> BSOD (or 50% of the time straight to BIOS)

In the app which is currently on your Netduino, is it writing out lots of Debug info?
Nope - it just prints an "I'm alive" message every 10 seconds from the main thread.
The app is a little HTTP server hosting a SilverLight client, so it's just sitting idle waiting for a connect.

I also observe that moving to a different USB port at the unresponsive stage (before the BSOD) buys more time so it's like there's a leak per port that hits some limit (hence the reference to nt!ExAllocatePoolWithTag+0x11 in the stack trace.

Got it - I'd not spotted your edit with the debug version just an hour earlier.What other files do you need?
