Prоblem: Librаry Mаnаgement System Yоu are tasked with building a simple Library Management System in C#. The applicatiоn should allow the user to manage books and patrons. The system will consist of multiple classes and forms to handle different parts of the program. It should also save and retrieve data from files. Requirements: Classes Create a Book class with the following properties: Title (string) Author (string) ISBN (string) IsAvailable (bool, default to true) Create a Patron class with the following properties: Name (string) PatronID (string) BorrowedBooks (List of Book) Create a Library class to manage: A list of Book objects A list of Patron objects Methods for adding/removing books and patrons, checking out books, and returning books. Forms Main Form: Provide buttons for "Manage Books" and "Manage Patrons." Manage Books Form: Allow users to add, edit, and remove books. Display the current list of books in a grid or list. Manage Patrons Form: Allow users to add, edit, and remove patrons. Display the current list of patrons in a grid or list. Checkout Form: Allow users to select a patron and a book to check out. Ensure that books cannot be checked out if they are unavailable. File Handling Save the list of books and patrons to separate files (books.txt and patrons.txt). Load the data from these files when the application starts. Error Handling and Searching Implement error handling for invalid input (e.g., duplicate ISBNs, empty fields). Add a search feature for books and patrons. Deliverables: A fully functional C# application meeting the requirements above. Code should be well-organized with proper comments explaining each class and method.
