New Post: How to query form xml data using odata

I would guess you would do this (basically include your namespace and replace IPage with program - I also renamed the controller class here:

using System.Linq;
using System.Web.Http;
using System.Web.Http.OData.Query;
using Composite.Data;
using Composite.Data.Types;
using ch7.program;

namespace Composite.Controllers
{

public class ProgramsController : ApiController
{
    [Queryable]
   public IQueryable<program> Get(ODataQueryOptions<program> options)
    {
        using (var c = new DataConnection())
        { 
            var querySettings = new ODataQuerySettings();

            return options.ApplyTo(c.Get<program>(), querySettings).Cast<program>().ToList().AsQueryable();
       }
    }
}

}

I find it a bit weird that your type has the same name as your namespace (both have "program") so if the above doesn't compile, look into this.
