例如我有这个类：

public class UnitOfWork : IUnitOfWork
{
    private readonly ApplicationDbContext _context;

    public IProductRepository Products { get; private set; }
    public ICategoryRepository Categories { get; private set; }
    public IPhotoRepository Photos { get; private set; }

    public UnitOfWork(ApplicationDbContext context, IProductRepository productRepository,
        ICategoryRepository categoryRepository, IPhotoRepository photoRepository)
    {
        _context = context;
        Products = productRepository;
        Categories = categoryRepository;
        Photos = photoRepository;
    }

    public int Complete()
    {
        return _context.SaveChanges();
    }

    public Task<int> CompleteAsync()
    {
        return _context.SaveChangesAsync();
    }

    public void Dispose()
    {
        _context.Dispose();
    }

    public async …
