In this C# code, why .net throw an exception on line return (MyList)this.OrderBy(p => p.Name).ToList(); ?

class Pet
public string Name { get; set; }
public int Age { get; set; }

class MyList : List<Pet>

public MyList SortByName()
return (MyList)this.OrderBy(p => p.Name).ToList();

Re: OrderBy
Here, ToList() returns a List<Pet>, not a MyList. You can't cast the result of ToList() to MyList.
