After scouring the web I managed to write a small class library that allows you to use Windows® Image Acquisition 2.0 lib to scan multiple images from scanners with an auto document feeder.

So its plain and simple to use and also contains a Win forms test app.

private void button2_Click(object sender, EventArgs e)
{
        ADFScan  scanner = new ADFScan();
        scanner.Scanning += new EventHandler<WiaImageEventArgs>(_scanner_Scanning);
        scanner.ScanComplete += new EventHandler(_scanner_ScanComplete);
        ScanColor selectedColor = ScanColor.BlackWhite;
        int dpi = 300;//some scanners have a problem if you set a lower DPI
        scanner.BeginScan(selectedColor,dpi );
       //ADFScan will now raise a Scanning event for EACH document scanned.
       //then scan complete once there are no more documents to scan.
}
void _scanner_ScanComplete(object sender, EventArgs e)
{
        MessageBox.Show("Scan Complete");
}
void _scanner_Scanning(object sender, WiaImageEventArgs e)
{//e.ScannedImage is a System.Drawing.Image
           e.ScannedImage.Save(filename, ImageFormat.Jpeg);//FILES ARE RETURNED AS BITMAPS
}

###Notes

This lib references WIA 2.0, which is available by default on Vista and higher.

This works for Windows XP SP1 onward but you need to install Windows® Image Acquisition Automation Library v2.0 You may also need to run :

regsvr32.exe wiaaut.dll
