Why .Length doesn't work?

[sea0920]

The code below works fine if I call .length instead of .Length.
Why does this happen? Did C# string[] already turn into javascript array before calling .Length?

class Program
    {
        public class Foo
        {
            public string[] MyStrings { get; set; } = { "abc", "def" };
        }

        static void Main(string[] args)
        {
            var engine = new Engine();

            var result = engine
            .SetValue("Foo", typeof(Foo))
            .Evaluate("new Foo().MyStrings.Length") // Changing Length to length works.
            .ToString();

            Console.WriteLine(result);
        }
    }

I think in that case Jint does automatic conversion on the fly as ArrayInstance so it won't have any non-JS-properties. If you don't want for that to happen, you can configure MemberAccessor in interop options to return something else, like ObjectWrapper, but then you will lose the array behavior like find etc.
