NEED HELP IN C# ONLY.

Consider a simplified program, where we can ONLY draw circles and rectangles on the canvas (no need to consider other shapes). Choose one of these languages: C++/C#/Java, and write down some pseudo-codes (i.e. doesnt need to be grammatically accurate) for the following questions.

1. Define two classes for a Circle and a Rectangle. For both classes, we would also like to know where the center of the circle/rectangle is, and be able to get the area of the circle/rectangle.

2. Obviously, these two classes share some common characteristics. Define a Shape class that encapsulates these common characteristics. What is the name of the relationship between the Rectangle/Circle class and Shape class, and what do you need to change about your codes in Q1? Also, why do we want/need the Shape class at all?

3. Should you be able to draw an unspecified Shape on the canvas? Or does it have to be a rectangular or circle? What does this mean about the Shape class? Hint: Im looking for the word abstract in your answer.

4. Also note that, the Shapes above all have colors, fills, shades, outlines, etc. To simplify it, lets combine all of these aesthetic elements of the Shape into one thing, and call it the Style of the Shape. If we want to include these information, what changes would you need to make to your previous codes?

5. Should Style be its own class? (Hint: yes). What is the relationship between Shape and Style in your code/design? Hint: your answer should be one or more of the following: association, aggregation, composition, inheritance.

6. Now, the user wants to draw something on the canvas. There are many ways to do this, but lets follow this method: there is a Canvas class, with a draw function. The user decides upon the shape first, then clicks on the canvas, and the draw function is called, and the shape shows up on the canvas. Write the sketch codes for the Canvas class and the draw function in this scenario.

7. Whats the relationship between Canvas and Shape: association, aggregation, composition, inheritance? Compare this relationship to the relationship between Shape and Style, what are the differences, if there are any? Explain what would happen to the Shape instances on a Canvas instance, when you delete a Canvas instance?What would happen to the Style instances when you delete a Shape instance? (20pts)
