ERR_CONNECTION_RESET返回包含对象子集合的异步

Question

我正在构建一个网络核心堆栈并将这些层实现为异步。

我有以下客户存储库代码，由web api层调用

 public class CustomerRepository : ICustomerRepository
{
    //interface this up
    private DbContextOptionsBuilder<SykesTestContext> optionsBuilder = new DbContextOptionsBuilder<SykesTestContext>();
    public CustomerRepository(string connection)
    {
        optionsBuilder.UseSqlServer(connection);
    }
    public async Task<List<Dom.Customer>> GetAll()
    {
        List<Dom.Customer> customers = new List<Dom.Customer>();
        var efCustomers = new List<Ef.Customer>();

        using (var customerContext = new TestContext(optionsBuilder.Options))
        {
            efCustomers = await customerContext.Customer
                                   .Include(cust => cust.Address)
                                   .Include(cust => cust.Telephone)
                                   .ToListAsync();

            foreach (var customer in efCustomers)
            {
                customers.Add(Mapper.Map<Ef.Customer, Dom.Customer>(customer));
            }
        }

        return customers;
    }


}

API调用方法

 [Produces("application/json")]
[Route("api/Customers")]
public class CustomersController : Controller
{
    ICustomerRepository _customerRepository;
    public CustomersController(ICustomerRepository customerRepository)
    {
        _customerRepository = customerRepository;
    }

    public async Task<List<Customer>> Get()
    {
        try
        {
            var customers = await _customerRepository.GetAll();
            return customers;
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
}

如果我发表评论＆＃34;包括＆＃34;那一切都运转正常。

如果我使用includes（构建对象子集合），我在浏览器中遇到以下错误：net :: ERR_CONNECTION_RESET并且只返回部分json对象？

有什么想法吗？

 public partial class Customer
{
    public Customer()
    {
        Address = new HashSet<Address>();
        Telephone = new HashSet<Telephone>();
    }

    public int Id { get; set; }
    public int ClientId { get; set; }
    public int TypeId { get; set; }
    public string FirstName { get; set; }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
    public int? ExternalId { get; set; }

    public virtual ICollection<Address> Address { get; set; }
    public virtual ICollection<Telephone> Telephone { get; set; }
}

域模型

public class Customer
{
    public int Id { get; set; }
    public int ClientId { get; set; }
    public int TypeId { get; set; }
    public string FirstName { get; set; }
    public string MiddleName { get; set; }
    public string LastName { get; set; }
    public int? ExternalId { get; set; }

    public virtual ICollection<Address> Address { get; set; }
    public virtual ICollection<Telephone> Telephone { get; set; }
}
