Entity Framework Core nullable foreign key

Question

I am having trouble getting a list of entities where a foreign key value could be null.

The Models:

public class Company
{
    [Key]         


        

Answer 1

Supposing that it did actually return mary, what would you expect her CompanyId to be? I would suspect null (what else could it be?), in which case your model is wrong and public int CompanyId { get; set; } should be public int? CompanyId { get; set; }
