Overview
A production-ready .NET CRUD application demonstrating clean layered architecture, SOLID principles, and real-time SignalR updates. Built as a personal reference implementation for enterprise .NET patterns including the Repository pattern, dependency injection, and AutoMapper.
Challenges
- Structuring a Blazor Server application that cleanly separates data access, business logic, and presentation concerns
- Implementing real-time updates without tight coupling between the SignalR hub and business logic layers
- Achieving meaningful test coverage on a Blazor Server component architecture
Solutions
- Applied strict layered architecture: Data Access → Business Logic → Presentation, with interfaces at every boundary
- Injected the SignalR hub as a notification service, keeping business logic decoupled from transport concerns
- Wrote xUnit tests targeting the service and repository layers independently, achieving 85% coverage
