i have gsm modem by this i want to connect windows service, and download new application version file, and save it into SD, after download i want to update my application from SD, so how to do this can someone help me.
FEZ Panda II.
For gsm:
http://code.tinyclr.com/project/278/gsm-driver/
For the rest of it:
take a look at Pyxis2 code it has everything you need.
thanks but i dont need gsm modem driver,
an one question how i can get my app hex file?
Read documentation:
Hint: Paragraph title is “Obtaining the Application File”
need your help please :((
here is my code which don’t works 
here comes exeption:

I don’t see where you call AccessBootloader. Follow the instructions in the documentation. Have you looked at Pyxis2 code?
i had AccessBootloader but it gives me exeption and then removed it
only what i need is to update my program from sd, and someone has some small source code.
i have Fez Panda II.
yes i looked at pyxis code but there i could not find there also accessbootloader.
this is my new source code but still nothing
private void EnsureLogFile(string path)
{
if (!File.Exists(path))

using (var fs = new FileStream(filename, FileMode.Append, FileAccess.Write))
{
var sw = new StreamWriter(fs);
Debug.Print("writing: " + input);
sw.WriteLine(input);
sw.Close();
fs.Close();
}
}

{
var fileName = GetRootDirectory();
if (fileName != null)

To find what you need in Pyxis 2:
Enabling/Accessing: /Progam.cs
Updating from SD: Pyxis2Updater/Program.cs
