Infrastructure Layer

Project: KeDevO.YardPro.Infrastructure Type: .NET 10.0 Class Library

Implements all external concerns — database persistence (EF Core), repository patterns, file storage, security, logging.

Architecture Role

Domain → Infrastructure → Application
              ↕
         Database (SQLite)
         File System (uploads/)

Persistence

AppDbContext (EF Core + SQLite)

Entity configurations in Persistence/Configurations/ — one per entity.

Repositories

Generic Repository (Repository<T>)

Standard CRUD operations for all entities.

Specialized Repositories

Extended repositories with domain-specific queries (filtering, includes, pagination).

Security

Password Hashing (DefaultPasswordHasher)

Parameter	Value
Algorithm	PBKDF2
Hash function	SHA-256
Iterations	120,000
Salt length	16 bytes
Key length	32 bytes
Storage format	{iterations}.{base64salt}.{base64key}

Storage

LocalDiskMediaStorage

Setting	Value
Base path	{WebRootPath}/uploads/
Vehicle media	uploads/vehicles/{vehicleId}/{guid}.{ext}
Part media	uploads/parts/{partId}/{guid}.{ext}
File naming	GUID-based to prevent conflicts

Utilities

• VinValidator — ISO 3779 VIN validation

Contributing Guidelines

1. All database access through repositories — never inject DbContext directly
2. Migrations only forward — never edit existing migrations
3. Entity configs in Persistence/Configurations/
4. Interface-first — define in Interfaces/ before implementing
5. No domain logic — Infrastructure handles persistence and I/O only
