I found great solution in this blog if someone will need it in the future

OperationContext clientContext = OperationContext.Current;
clientContext.OperationCompleted += new EventHandler(delegate(object sender, EventArgs args)
   {
      if (fileStream != null)
         fileStream.Dispose();
   });
