我使用MVC 6 rc1与EF 7 rc 1 Code First Model通过web api控制器检索数据.
我有3个类似于下面的表.

class Product
{
    public int Id { get; set; }
    public string SomeProperty { get; set; }
    public virtual ICollection<Categorization> Categorizations { get; set; }
    public DateTime SomeProperty2 { get; set; }
    public string SomeProperty3 { get; set; }
    public string SomeProperty4 { get; set; }

}

// NOTE: Entity key should be (ProductId,CategoryId)
class Categorization
{
    public int ProductId { get; set; }
    public Product Product { get; set; }

    public int CategoryId { get; set; }
    public Category Category { get; set; }
}

class Category
{
    public int Id { get; set; }
    public ICollection<Categorization> Categorizations { get; set; }
}

我的控制器：

[ActionName("searchProducts")]
        public IEnumerable<Product> searchProducts(string searchText,int? id)
        {
          var ret= db.Products
                .Include(s => s.Categorizations).Take(2).ToList();
          return ret;
        }

下面是我的Startup.cs ConfigureServices部分.

services.AddMvc()
                .AddJsonOptions(options=>
                {
                    options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
                    options.SerializerSettings.MissingMemberHandling = Newtonsoft.Json.MissingMemberHandling.Ignore;
                });
            services.AddCors();

            var connectionString = Configuration.GetSection("Data:DefaultConnection:ConnectionString").Value;

            services.AddEntityFramework()
                .AddsqlServer()
                .AddDbContext<ContractsContext>(options => options.UsesqlServer(connectionString));


            services.AddSingleton(_ => Configuration);
            services.AddSingleton<IContractRepository,ContractRepository>();

当我调用api时,我得到的错误是“在Fiddler中,Chunked body没有正确地终止0大小的块”.在fiddler结果集中,我只看到具有属性的预期结果集的第一个对象,直到填充了分类并且在此之后没有属性和剩余对象(不完整的JSON数据).如果我在结果集中不包含分类,则它可以正常工作.我错过了什么吗？
注意：EF正确地返回数据,但它在api调用中被分块,客户端无法完整地读取数据.

services.AddMvc()
                .AddJsonOptions(options =>
                {
                    options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
                });
