New Post: No supported Bluetooth protocol stack found.

I'm writing window CE application using VS2008 microsoft .net framework v.3.5 SP1 and window mobile 5.0 and inTheHand.Net.Personal runtime version v2.0.50727 version 3.7.1102.0.
and my laptop is Dell latitude with Bluetooth radio

• Dell Wireless 375 Bluetooth Module
• Microsoft Bluetooth Enumerator
  

When I debug through USA windows mobile 5.0 pocket PC emulator and connect the Bluetooth from thermometer I got 'No supported Bluetooth protocol stack found.' and the following :

Here is my code :
BluetoothAddress addr = BluetoothAddress.Parse("008098097690");

        BluetoothEndPoint ep = new BluetoothEndPoint(addr, BluetoothService.SerialPort);
        if (BluetoothRadio.IsSupported)
        {
            MessageBox.Show("Supported");
        }
        else
        {
            MessageBox.Show("Not supported");
        }
        BluetoothClient cln = new BluetoothClient();
        BluetoothSecurity.PairRequest(addr, "0000");
        cln.Connect(ep);

        while (true)
        {
            Stream mStream = cln.GetStream();
            byte[] received = new byte[1000];
            string txtRec = "", txtRet = "";
            int n, i, tempVal;

            try
            {
                mStream.Read(received, 0, received.Length);
                txtRec = (Encoding.ASCII.GetString(received, 0, received.Length).ToString().Replace("\0", "")).Trim();
                n = txtRec.IndexOf("H");
                if (n != -1 && txtRec.Length >= 8)
                {
                    txtRec = txtRec.Substring(n + 4, 4);
                    i = txtRec.IndexOf(".");
                    if (i != -1) txtRec.Substring(0, i);
                    tempVal = Convert.ToInt32(string.Join(null, System.Text.RegularExpressions.Regex.Split(txtRec, "[^\\d]")));
                    txtRet = tempVal.ToString();
                    return txtRet;
                }
                mStream.Flush();

            }
            catch (IOException ex) { MessageBox.Show(ex.Message); }
            return txtRet;
        }

I have tried several version of InHand Dll but it's not working either and also have copy 32feetWidcomm.dll and btwapi.dll from C:\Program Files\32feet.NET\Broadcom\Win32-x64 to my debug folder. it didn't work too.
But when I write the window application with vs2010 the same code just working fine.

Can you suggest me what should I do to correct it?
