InnerException:
It has something to do with the conversion of the C# GeographyPoint to its json/javascript equivalent. Can someone tell me what I need to do to make this work? Since there seems to be no JayStack data importers, I need to make this work in order to initialize my data:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Spatial;
using System.Text;
using System.Threading.Tasks;
namespace AirportDataImporter
{
class Program
{
static void Main(string[] args)
{
var db = new AirportDB.mydatabaseService(new Uri("https://open.jaystack.net/c72e6c4b-27ba-49bb-9321-e167ed03d00b/6494690e-1d5f-418d-adca-0ac515b7b742/api/mydatabase/"));
var airport = new AirportDB.Airport();
airport.Abbrev = "Foo";
airport.Name = "Bar";
airport.GeoLocation = GeographyPoint.Create(51.87796, -176.64603);
db.AddToAirport(airport);
db.SaveChanges();
}
}
}
Additionally, the Visual Studio generated service reference hard codes odata version 2 for which jaydata also throws a different exception. I hand edited the generated proxy file to v3 to fix this. This is not an ideal way to do this. Any pointers in that regard?
