ASP.NET MVC Application with Clean Architecture

This project is a robust ASP.NET MVC application built using Clean 3-Layered Architecture (Presentation, Business, Data Access) and Entity Framework Core (Code-First). It demonstrates advanced ASP.NET Identity management, structured access control, and scalable design patterns suitable for real-world enterprise applications.

---

Architecture

• Presentation Layer: Handles the UI, MVC Controllers, Views, and AJAX interactions.
• Business Layer: Contains services, business logic, and manages coordination between Data Access and Presentation layers.
• Data Access Layer: Implements Entity Framework Core (Code-First) with migrations for database management.

---

Authentication & Authorization

• ASP.NET Identity integrated for user management.
• Advanced Role-Based Access: Admin and User roles separated with structured permissions.
• Remember Me feature for persistent authentication.
• Structured Access Control: Different permissions for Admin and regular users.

---

Design Patterns & Best Practices

• Generic Repository: Reusable repository for CRUD operations on any entity.
• Unit of Work: Ensures atomic transactions and clean data handling.
• AutoMapper: Maps between entities and ViewModels seamlessly.
• Dependency Injection (DI): Applied across all layers to ensure decoupling and testability.

Features & Functionality

• CRUD Operations: Full Create, Read, Update, Delete for all entities (Department, User, Role).
• AJAX Real-Time Search: Instant filtering of data without page reloads.
• Soft Delete: Ensures records can be "deleted" safely without permanent removal.
• User & Role Management: Add/Remove users from roles dynamically with proper validation.
• Structured Access Control: Ensures only authorized users can access sensitive operations.
