public Form1()
{
    InitializeComponent();
    ICSharpCode.AvalonEdit.TextEditor textEditor = new ICSharpCode.AvalonEdit.TextEditor();
    textEditor.ShowLineNumbers = true;
    textEditor.FontFamily = new System.Windows.Media.FontFamily("Consolas");
    textEditor.FontSize = 12.75f;

    string dir = @"C:\Temp\";
    #if DEBUG
    dir = @"C:\Dev\Sandbox\SharpDevelop-master\src\Libraries\AvalonEdit\ICSharpCode.AvalonEdit\Highlighting\Resources\";
    #endif

    if (File.Exists(dir + "CSharp-Mode.xshd"))
    {
      Stream xshd_stream = File.OpenRead(dir + "CSharp-Mode.xshd");
      XmlTextReader xshd_reader = new XmlTextReader(xshd_stream);    
      // Apply the new syntax highlighting definition.
      textEditor.SyntaxHighlighting = ICSharpCode.AvalonEdit.Highlighting.Xshd.HighlightingLoader.Load(xshd_reader, ICSharpCode.AvalonEdit.Highlighting.HighlightingManager.Instance);
      xshd_reader.Close();
      xshd_stream.Close();
    }
    //Host the WPF AvalonEdiot control in a Winform ElementHost control
    ElementHost host = new ElementHost();
    host.Dock = DockStyle.Fill;
    host.Child = textEditor;
    this.Controls.Add(host);
}
