Entity Framework creates foreign key objects instead of using those that are already available

Question

my current project is based on Entity Framwork code-first. I have three types: Task, TaskType and Module.

    public class Task
    {
        public int ID {         


        

Answer 1

I'm new to entity framework but I just ran into the same issue, where my foreign key property was populated but the navigation object was null, with code like:

public class EntryRecord
{        
    [Key]
    public int Id { get; set; }
}
public class QueueItem 
{       
    [Key]
    public int Id { get; set; }


    public int EntryRecordId { get; set; }

    [ForeignKey("EntryRecordId")]
    public EntryRecord EntryRecord { get; set;}

}

Setting the navigation property to virtual fixes the problem and enables lazy loading :

    [ForeignKey("EntryRecordId")]
    public virtual EntryRecord EntryRecord { get; set;}
