Uploading files from WP7 device to a web server using a web service?

How do you upload files from WP7 to a web server using a web service? Also when the file is there and is processed how can you download the processed file back down to the WP7 device?

Well, you could give us some more clues about how is your webservice, is it an asmx, wcf, php, java? Does it have a wsdl or you are using REST?

Anyway, I will do some assumptions, because if you have a wsdl then you only have to add a web reference and use it. If you need to write your own uploader you can use, for example, the WebClient class for pushing data to your webservice.

// I assume you have the image into a stream called imageStream
// and that you provide your url into the serviceUri variable

WebClient client = new WebClient();

//here you indicate what to do when the stream is opened
client.OpenWriteCompleted += (sender, e) =>
{
  //now write the data
  //in e.Result you have the destination stream

  byte[] buffer = new byte[32768];
  int readCount;

  while ((readCount = imageStream.Read(buffer, 0, buffer.Length)) != 0)
  {
    e.Result.Write(buffer, 0, readCount);
  }
  e.Result.Close();
  imageStream.Close();
};

 //and here the call that starts your async operation
 client.OpenWriteAsync(serviceUri);
