Create a C console application named PackageDemo that declar

Create a C# console application named PackageDemo that declares and demonstrates objects of the package class and its descendants. The package class includes auto-implemented properties for an id number, recipients name, and weight in ounces. The class also comntins a delivery price feild that is set when the weight is set as $5 for the first 32 ounces and 12 cents per ounce for every ounce over 32. b. Create a child class named InsuredPackage, which includes a field for the package\'s value. Override the method that sets a Package\'s delivery price to include insurance, which is $1 for packages valued up to $20 and $2.50 for packages valued $20 or more.
