## Overview

This is a Windows WinForms library-catalog app. A user opens the main screen to browse or search books, then adds, edits, or deletes a selected record; the main form coordinates dialogs and repository operations, which persist book data through EF Core to a local SQLite database. The README also documents EF Core migrations. Source excerpts show the main runtime calls; migration implementation was not sampled, so its connection to runtime is left unverified.

Main entry points: [`UI/MainForm.cs`](https://github.com/muludag718/librarymanagementsystem/blob/main/UI/MainForm.cs) (Catalog and search), [`Database/LibraryDbContext.cs`](https://github.com/muludag718/librarymanagementsystem/blob/main/Database/LibraryDbContext.cs) (EF Core context), [`Program.cs`](https://github.com/muludag718/librarymanagementsystem/blob/main/Program.cs) (App startup), [`UI/ProcessForm.cs`](https://github.com/muludag718/librarymanagementsystem/blob/main/UI/ProcessForm.cs) (Book editor)
