Question

我有以下实体：

public DbSet<WFPP> WFPPs { get; set; }
....
[Table("PlanningUnit")]
public class PlanningUnit
{
    public PlanningUnit()
    {

    }

    public int PlanningUnitId { get; set; } 
    public Region Region { get; set; }       

}


[Table("WFPP")]
public class WFPP
{
    public WFPP()
    {
        AgencyList = new List<PlanningUnit>();
    }

     public int Id { get; set; }

    public List<PlanningUnit> AgencyList;

}

我尝试按如下方式加载实体：

      var test= _context.WFPPs.Where(x => x.Id==0).Include(x => x.AgencyList).ToList();

我收到以下错误：

The expression '[x].AgencyList' passed to the Include operator could not be bound.

我无法弄清楚导致此错误的原因，我似乎无法在网上找到太多信息。感谢。

  I tested with console app you just need to add get and set.

  [Table("WFPP")]
    public class WFPP
    {
        public WFPP()
        {
            AgencyList = new List<PlanningUnit>();
        }

         public int Id { get; set; }

      ///    your are missing get and set 
         public ICollection<PlanningUnit> AgencyList { get; set; }

    }

EF核心表达无法绑定
