Complete Role Management System in ASP.NET Core with MongoDB | CQRS & Clean Architecture Tutorial

Welcome to this comprehensive tutorial where we build a production-ready Role Management System for a Soccer League application using ASP.NET Core, MongoDB, and Clean Architecture principles!
What You'll Learn
In this video, I'll walk you through a complete implementation of a role-based access control system featuring:
Architecture & Design Patterns:

Clean Architecture with clear separation of concerns across Application, Infrastructure, and API layers
CQRS (Command Query Responsibility Segregation) pattern using MediatR
Repository Pattern with MongoDB integration
AutoMapper for object-to-object mapping
FluentValidation for robust input validation

Core Features Implemented:

Complete CRUD operations for role management
Advanced filtering and pagination support
Permission management system with granular access control
System roles vs custom roles differentiation
Soft delete functionality for data integrity
Comprehensive validation rules and error handling

Technical Stack:

ASP.NET Core Web API
MongoDB as the NoSQL database
MediatR for implementing CQRS pattern
AutoMapper for DTO mapping
FluentValidation for request validation
Swagger/OpenAPI documentation

Key Highlights:

Seven pre-configured system roles: Administrator, Manager, Referee, Team Manager, Player, Fan, and User
Dynamic permission assignment and management
Query parameters for flexible data retrieval
RESTful API design with proper HTTP status codes
Comprehensive error handling and logging
Production-ready code with XML documentation

Project Structure Covered:

DTOs (Data Transfer Objects) for API contracts
Command and Query handlers following CQRS
Custom validators with async validation rules
Repository implementation with MongoDB drivers
API controllers with full Swagger documentation
Database seeding for initial role setup

Whether you're building a sports management system, enterprise application, or any system requiring role-based access control, this tutorial provides a solid foundation you can adapt to your needs.
