Took a look and the bug appears to be inside the DynamicHelper type. If you debug this application with Just My Code disabled you'll see this block throws everytime a request for OrderID or ObjectID is made

            var dynamicHelper = new DynamicHelper();
            var getterSite = dynamicHelper.GetGetterSite(dynamicMetaObject.GetType(), propName);
            object result = getterSite.Target.Invoke(getterSite, dynamicMetaObject);
            return result;

When this code is fixed up to not throw (just using slow reflection to grab the members) then everything works just fine. The bug appears to be in how DynamicHelper generates theses getters.
