如果automapper的集合为空，为什么会创建空的集合实例？这是我的配置

public class MapperProfile : Profile
{
    protected override void Configure()
    {
        AllowNullCollections = true;
        AllowNullDestinationValues = true;
        Mapper.CreateMap<User, DAL.Models.User>();
        Mapper.CreateMap<DAL.Models.User, User>();
        Mapper.CreateMap<Role, DAL.Models.Role>();
        Mapper.CreateMap<DAL.Models.Role, Role>();
        Mapper.CreateMap<Task, DAL.Models.Task>();
        Mapper.CreateMap<DAL.Models.Task, Task>();
        Mapper.CreateMap<TaskReport, DAL.Models.TaskReport>();
        Mapper.CreateMap<DAL.Models.TaskReport, TaskReport>();
        Mapper.CreateMap<Project, DAL.Models.Project>();
        Mapper.CreateMap<DAL.Models.Project, Project>();
    }
}

我的模型具有相同的属性：

public class User
{
    public virtual List<Task> Tasks { get; set; }

    public virtual List<Role> Roles { get; set; }

    public virtual List<TaskReport> TaskReports { get; set; } 
}

在Global.asax的MVC项目中，仅添加我的个人资料，如下所示：

Mapper.AddProfile(new BL.MapperProfile());

谢谢！

我知道已经问过类似的问题，并且我已经阅读过，但是我不明白为什么框架4.5.2会发生这种情况。我已经发布ClickOnce，并且在安装4.5.2时需要.net Framework 4.5 。我可以在调试模式下运行它或构建它而没有任何问题。有人可以回答为什么会发生这种情况吗，我该如何解决呢？
