Cannot get InputBox after adding reference to Microsoft.VisualBasic

I did what is said here http://www.pcreview.co.uk/forums/thread-1899493.php but in intellisense I only get Microsoft.VisualBasic.VBCodeProvider ???

step 1: Add refernce Microsoft.VisualBasic

step 2:

private void button1_Click(object sender, EventArgs e)
{
  string result = Microsoft.VisualBasic.Interaction.InputBox("kkk","text", "", 10, 20);

  MessageBox.Show(result);
}

Step 1: Check if you really added the reference ;-)

Microsoft.VisualBasic.VBCodeProvider is located in System.dll, which is referenced for every new project. It seems to me as if you're not referencing Microsoft.VisualBasic.dll at all.

You need to add a reference to Microsoft.VisualBasic, not to the Microsoft.VisualBasic.Compatability library.
