Library App

Description

Library App is a console-based library management system implemented in C# using .NET 8.0. It allows users to manage patrons, books, and loans through a simple console interface. The application uses JSON files for data storage and supports operations such as searching for patrons, viewing patron details, managing loans, and renewing memberships.
