Hierarchical relationship convention is case sensitive

[abe545]

These should support the convention:

public class Parent
{
    public int ID { get; set; }
    public IEnumerable<Child> Children { get; set; }
}

public class Child
{
    public int Parentid { get; set; }
    public int Childid { get; set; }
}

However, an exception is thrown that states the key can't be determined to produce the mapping.
