Create WPF Simple Visual-Studio-Like Designer

The application will allow user to create a simple window with some controls in a similar manner to visual-studio designer. Window will start with a grid layout panel size 10X10 (auto-size for all rows and columns) on the main section, a toolbox on the left side and a properties panel on the right side. The toolbox will contain the elements: Label (text, font, font style, font size) Image (image file name) Flow Panel (user will be able to add more elements to this panel in a flow style) Stack Panel (user will be able to add more elements to this panel in a flow style) Adding elements is done via drag-and-drop, just like VS. User can resize control by dragging its outline – this will increase/decrease the row/col span accordingly (the drag should be 'snap-to-grid', that is, the drag 'shadow' should jump to the next row/col line immediately). The layout needs to be saved to xml file and loaded from that file. each control in the UI will be represented as a class in the xml file. A button 'Run' will open a new window with the created layout.
