Unit of Work Pattern in .NET — Why You Need It and How to Implement It

The Unit of Work pattern manages database transactions by tracking changes across multiple entities and ensuring they're committed together or not at all. This design pattern provides data consistency, abstracts transaction management from business logic, improves efficiency through batching, and enhances testability. The implementation involves creating repository interfaces, implementing them with Entity Framework Core, defining a Unit of Work interface, and coordinating multiple repositories within a single transaction boundary.
