A WPF (C#) application that is a primitive graphics program. This program’s purpose is to create and manipulate a set of circular shapes shown on a canvas. Your program must:

• Provided a button that creates a new circle on the canvas at a random visible location,
• Allows the user to “drag” one of the circles to a new location on the canvas, and
• Provided buttons that perform undo and redo operations.
• Undoing creating a circle will delete that circle. Redoing it will make that appear at the point where it was initially created.
• Undoing moving a circle will return it to the position where it was at the beginning of the mouse operation.
• Redoing it will make it appear at the location where it was at the end of the mouse operation.
• The undo (and redo) buttons will be disabled if there are no undo (or redo) operations that can be performed.

• MVVM-based design
• Prism Framework
• A WPF Library has a custom panel to arrange the shapes
