public class CustomerRepository : ICustomerRepository { private readonly ApplicationDbContext _dbContext; public CustomerRepository(ApplicationDbContext dbContext) { _dbContext = dbContext; } public async TaskThis example uses Entity Framework to implement a repository for a `Customer` entity, with methods for retrieving all customers, retrieving a customer by ID, adding a new customer, updating an existing customer, and deleting a customer. The `ICustomerRepository` interface would define these methods, allowing the implementation to be easily swapped out with another repository framework if needed. Overall, this code is an example of using Entity Framework as a package/library to implement a repository pattern in C#.GetById(int id) { return await _dbContext.Customers.FindAsync(id); } public async Task > GetAll() { return await _dbContext.Customers.ToListAsync(); } public async Task Add(Customer customer) { await _dbContext.Customers.AddAsync(customer); await _dbContext.SaveChangesAsync(); } public async Task Update(Customer customer) { _dbContext.Customers.Update(customer); await _dbContext.SaveChangesAsync(); } public async Task Delete(int id) { var customer = await GetById(id); _dbContext.Customers.Remove(customer); await _dbContext.SaveChangesAsync(); } }
