I have the following and it works for me.

namespace BusinessApplication2.Web
{
    using System.ComponentModel.DataAnnotations;
    using System.Linq;
    using System.ServiceModel.DomainServices.Hosting;
    using System.ServiceModel.DomainServices.Server;

    [EnableClientAccess()]
    public class DomainService1 : DomainService
    {
        public IQueryable GetEntityOnes()
        {
            return null;
        }

        public IQueryable GetEntityTwos()
        {
            return null;
        }

        [Invoke]
        public SerializableResult GetSerializableResult(EntityOne one, EntityTwo two)
        {
            return new SerializableResult() { Result = "It woooooorrrked!" };
        }
    }

    public class EntityOne
    {
        [Key]
        public int Id { get; set; }
    }

    public class EntityTwo
    {
        [Key]
        public int Id { get; set; }
    }

    public class SerializableResult
    {
        public string Result { get; set; }
    }
}
