Invalid column when adding a foreginkey - entity-framework-core

Question

public class PIC
{
[Key]
public int Id { get; set; }
[ForeignKey("IMONumber")]
public int IMONumber { get; set; }
public string VesselName { get; set; }
public string PICOperation { get; set; }
public string PICChartering { get; set; }
}
public class VesselInfo
{
[Key]
public int Id { get; set; }
public string ImoType { get; set; }
public int IMONumber { get; set; }
public PIC PIC { get; set; }
}
When I call following:
var test1 = db.Vessels.ToList();
or
var test2 = db.Vessels.Include(p=>p.PIC).ToList();
I get an error saying PICId invalid column? And opointers?

Answer 1

i will recommend this:
Your PIC class is not connected with a foreign key your VeselInfo table so they are not related and you cannot get information about that. Try replacing your code and try again
public class PIC
{
[Key]
public int Id { get; set; }
public int IMONumber { get; set; }
[ForeignKey("IMONumber")]
public virtual IMON IMON
public string VesselName { get; set; }
public string PICOperation { get; set; }
public string PICChartering { get; set; }
}
public class VesselInfo
{
[Key]
public int Id { get; set; }
public string ImoType { get; set; }
public int IMONumber { get; set; }
public int PicId {get; set;}
[ForeignKey("PicId")]
public virtual PIC PIC { get; set; }
}
