C# Warning: No data for encoding 1252

Hello, I'm currently using windows 8 64-bit  OS and C# in Visual Studio 2010 64bit. I'm getting some warning when compiling. How can I fix this warning ?

MyCodes:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;

namespace SkillFeed_Downloader
{
  public partial class Form1 : Form
  {
  public Form1()
  {
  InitializeComponent();
  }

  private void btnfiledialog_Click(object sender, EventArgs e)
  {
  OpenFileDialog fd = new OpenFileDialog();
  fd.ShowDialog();
  filepath.Text = fd.FileName;
  filepath.Enabled = false;

  }

  private void btndownload_Click(object sender, EventArgs e)
  {
  WebClient client = new WebClient();
  client.Encoding = System.Text.Encoding.UTF8;
  string url = txturl.Text;
  string path = filepath.Text;
  client.DownloadFileAsync(new Uri(url), (path));
  client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);


  }

  void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
  {
  progressBar1.Value = e.ProgressPercentage;
  lblbytereceived.Text = e.BytesReceived.ToString();
  lbltotalbytes.Text = e.TotalBytesToReceive.ToString();
  }

  private void Form1_Load(object sender, EventArgs e)
  {
 
  }
  }
}
