EF Code First not generating table for ICollection

Question

I would like the below ICollection property in one of my data classes (let\'s call it \"Foo\")

public class Foo
{
    [Key]
    public int FooId { get; set;          


        

Answer 1

EF can only work with entity classes. Each entity class must have defined primary key so the minimum in your scenario is:

public class StringData
{
    public int Id { get; set; }
    public string Data { get; set; }
}

or worse

public class StringData
{
    [Key]
    public string Data { get; set; }
}

Now you can define collection of StringData to map it as related table:

public virtual ICollection AllowedBars { get; set; }
