title: wcf upload/download large files (i.e. Img, mp3) in chunks with windows service
body: <p>I have a window service and i want it to be able to upload/download large (around 4MB) files (Img, music etc.) in chunks.<br>
  I tried to do that by changing the 'maxBufferSize' 'maxRecivedMessageSize' etc. in both the service and client app.config files, but unfortunately it didn't work.<br>
  My question is how I can upload/download files in chunks. and if I can do that just with the App.config file?<br>
  Thank!</p>
