Array element introspection

Has anyone else run into this? Introspection on an array-typed field fails to yield the element type. Introspection on an array instance works. This fails in both 4.3 and 4.4.

namespace BrokenArrays
    public class TestClass
        public int[] intArray;
        public string[] stringArray;

    public class Program
        public static void Main()
            var test = new TestClass();

            var type = test.GetType();

            // This always fails - can't determine the element type by instrospection on a field
            var field = type.GetField("intArray");
            if (field.FieldType.GetElementType()==null)
                Debug.Print("failed to determine intArray element type");

            // Getting the type from an actual array instance succeeds
            test.intArray = new int[5];
