When I select a control, such as Button, keep dragging this control, and moving around on design window, Demo.XamlDesigner program report a assert error in UndoService.cs: line 101.
Probably reason is the correction in CreateComponentTool.cs: line 194 on lasted version.
I suggest deleting CreateComponentTool.cs: line 194 as the older version.
