Hi ccondo,

Are things working now for you, with this latest update?

Chris

I had same problem.

1. Install MF SDK

2. Install ND SDK

3. Install netmfvs2013.vsix

4. All works fine 

using(FileStream file = new FileStream(fileWrite, FileMode.OpenOrCreate, FileAccess.ReadWrite))
using (StreamWriter writer = new StreamWriter(file))
{
    writer.WriteLine("Hello");
    writer.WriteLine("SD");
}

Thanks sfx

At all, this code works fine, but my Windows 8 can't recognize SD after file writing, but i can read data programmatically. Amazing.

Solution: format e: /fs:FAT

Read\Write only from Netduino

I do not know what is going on, but i hate this "Magic". After several(approximately 100 (4 hours)) times of debugging application, it can some time work, some time did not work.Deployment Erasing and VS rebooting can some time help, some time no. I wasted a lot of time ... and i cant find any logic dependencies.

And again Reader works fine 

Default .Net application with SD Card works fine.

I use VS 2013 and last version of MF and Netduino SDK, also firmware on my board 4.3.1

Hello guys,

I have problem with SD card, when i read from it all fine, but when i try write i have Exception in System.IO

DirectoryInfo dir = new DirectoryInfo(@"\SD\");
bool dirExist = dir.Exists;
var files = dir.GetFiles();
string fileName = @"\SD\test.txt.txt";
string fileWrite = @"\SD\testWrite.txt";
bool fileExist = File.Exists(fileName);
OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
using (FileStream file = 
    new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite))

//using (FileStream file=
    new FileStream(fileWrite, FileMode.OpenOrCreate, FileAccess.ReadWrite))
//using(StreamWriter wr = new StreamWriter(fileWrite))
//{
//    wr.WriteLine("Hello");
//    wr.WriteLine("StreamWriter");
//}

using (StreamReader reader = new StreamReader(file))
{
    string line;
    while ((line = reader.ReadLine()) != null)
    {
        led.Write(true);
        Thread.Sleep(250);
        led.Write(false);
        Thread.Sleep(250);
     }
}

Exception raised in commented code

Can some one help me?
