title: Adding line WPF control on ToolBox
body: <p>I need to draw lines and dots (circles) in WFP. (VS 2010)</p>
  
  <p>I tried using Ellipse control for dots, but I don't have the line ones. 
  I however added <code>&lt;Line</code> element directly in XAML and this worked... 
  but how I have the line control in the toolbox?</p>
