The other day I was teaching a WPF course when one of the students asked me where is the “ Line ” shape in the Visual Studio Toolbox. I approach to show him, only to find out that this control is indeed missing from the Visual Studio 2010 Toolbox. Even if you search the alleged “ All WPF Controls” tab.. After a quick check I’ve found that this is not the only shape missing. The missing shapes are: Line , Path , Polygon , Polyline . And who knows which other controls are missing. Anyway, you can add...
