$3.$ You are tasked to design and develop a comprehensive C# program to simulate a basic library management system for Richfield. Your program must encompass classes representing a Library, Book, and Member entities. The Book class should encapsulate properties such as title, author, and availability status. Similarly, the Member class should encapsulate properties like name and studNumber.

The Library class must serve as the central hub for managing the library's resources and members. It should feature methods to facilitate the process of checking out and returning books, in addition to maintaining organized collections of both books and members.

$$ Create the three classes: Book, Member, and Library, each encapsulating relevant properties and methods.

$$ Book and Member classes represent books and library members,

$$ The Library class serves as the central hub for managing books and members, with methods for adding books, adding members, borrowing, and returning books.

$$ A list to store collections of books and members, offering flexibility and ease of use.

$$ The Main method in the Program class demonstrates the usage of these classes by creating instances of books, members, and the library, and simulating book borrowing and returning actions. $(25$ Marks$)$
