Repository and Unit of Work with EF Core

The Repository pattern abstracts data access, while Unit of Work coordinates changes.

Repository: Provides methods like Add, GetById, List for aggregates.

Unit of Work: Wraps SaveChangesAsync to commit a transaction.

EF Core's DbContext already acts as a unit of work and repository, but explicit repositories can enforce aggregate boundaries and domain-specific queries.

Architecture impact: Use repositories to keep application and domain layers independent of EF Core specifics.
