Servicestack JSV empty string deserialized as null

Question

It seems that JSV deserializes an empty string as null. The following test fails for JSV but passes for JSON.

    class Foo
    {
        public string String { get; set; }
    }

    [TestFixture]
    public class TestJsvEmptyString
    {
        [Test]
        public void TestJsv()
        {
            Foo orig = new Foo() { String = string.Empty };

            string jsv = orig.ToJsv();
            Foo fromJsv = jsv.FromJsv<Foo>();

            Assert.AreEqual(orig.String, fromJsv.String);
        }

        [Test]
        public void TestJson()
        {
            Foo orig = new Foo() { String = string.Empty };

            string json = orig.ToJson();
            Foo fromJson = json.FromJson<Foo>();

            Assert.AreEqual(orig.String, fromJson.String);
        }
    }

Thanks for a great package!

Empty strings are treated as null in the JSV Format, as it has no wire representation.

The problem is that Servicestack OrmLite serializes objects as JSV, and when read from database we encounter this problem. – user3009388 Nov 19 '13 at 16:55
@user3009388 Just don't distinguish between empty string and nulls, otherwise you'd have to avoid using JSV and not blob complex types in OrmLite. – mythz Nov 19 '13 at 17:11
