Entity Framework Mapping Entity To Itself
===

I have an entity that needs to contain a related entity of itself:

    public class Period
    {
    public int ID {get; set;}
    public DateTime StartDate {get; set;}
    public DateTime EndDate {get; set;}  
    public Period PriorPeriod {get; set;}  
    
    }

How can I achieve this using only POCOs or does this require a Fluent API Mapping?
