Can you give an example where you combined Repository and Unit of Work patterns?

Short answer: The Unit of Work coordinates multiple Repositories and commits changes in a single transaction. For example: public interface IUnitOfWork : IDisposable

Example code

{ IProductRepository Products { get; } IOrderRepository Orders { get; } int Complete();
}
public class UnitOfWork : IUnitOfWork
{
private readonly DbContext _context;
public IProductRepository Products { get; }
public IOrderRepository Orders { get; }
public UnitOfWork(DbContext context)
{
_context = context;
Products = new ProductRepository(_context);
Orders = new OrderRepository(_context);
}
public int Complete() => _context.SaveChanges();
public void Dispose() => _context.Dispose();
} This ensures atomic commits across repositories.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
