Answer the following questions:

Create a console application named Ch10_Exercise02 that creates a list of shapes, uses serialization to save it to the filesystem using XML, and then deserializes it back:

    // create a list of Shapes to serialize 
    var listOfShapes = new List<Shape> 
    { 
      new Circle { Colour = "Red", Radius = 2.5 }, 
      new Rectangle { Colour = "Blue", Height = 20.0, Width = 10.0 }, 
      new Circle { Colour = "Green", Radius = 8 }, 
      new Circle { Colour = "Purple", Radius = 12.3 }, 
      new Rectangle { Colour = "Blue", Height = 45.0, Width = 18.0  } 
    }; 

Shapes should have a read-only property named Area so that, when you deserialize, you can output a list of shapes, including their areas, as shown here:

    List<Shape> loadedShapesXml = serializerXml.Deserialize(fileXml)
    as List<Shape>; 
    foreach (Shape item in loadedShapesXml) 
    { 
      WriteLine($"{item.GetType().Name} is {item.Colour} and has an
      area of {item.Area}"); 
    } 

This is what your output should look like when you run the application:

Loading shapes from XML:
Circle is Red and has an area of 19.6349540849362
Rectangle is Blue and has an area of 200
Circle is Green and has an area of 201.061929829747
Circle is Purple and has an area of 475.2915525616
Rectangle is Blue and has an area of 810

Create a console application named Ch10_Exercise03 that queries the Northwind database for all the categories and products and then serializes the data using at least three formats of serialization available to .NET Core.

Which uses the least number of bytes?
