LibraryManagementSOAPApplication

WCF-based library management system with a console client, built in C# for Windows.

Features

• Add, update, and delete books from the library
• Check out and return books with availability tracking
• Search by ISBN, title, author, or availability status
• ISBN-13 format validation with automatic formatting (strips dashes and spaces)
• Detailed validation error messaging via typed WCF FaultExceptions
• Interactive console UI with y/n prompts and confirmation steps

Requirements

• .NET Framework 4.8 (Windows only)
• Visual Studio 2022 or later

Setup

1. Clone the repository
2. Open LibraryManagementService.sln in Visual Studio, make sure the project root is selected, and run it - this starts the WCF service (you'll know you were successful if a web browser opens; if a popup window opens, you have the wrong file selected in the solution explorer)
3. Open LibraryManagementClient.sln in a separate Visual Studio instance and run it - this launches the console client

⚠️ The service must be running before the client
