odata - WCF not returning service end point -

i trying return list of entities wcf data service. not using entity framework rather pulling data out of neo4j , returning asqueryeable . 404 error if run code saying url not found objectentitiesservice.svc?

here code: object

[dataservicekeyattribute("id")]     public class objectentity      {         public string id { get; set; }         public string name { get; set; }         public string entitytype { get; set; }         public int version { get; set; }         public string datetimecreated { get; set; }         public string status { get; set; }     } 

getting data:

    public partial class objectentitydata     {         static list<objectentity> objectentitylist;         static objectentityoperations objectentityops;         static objectentitydata()         {             var foundentities = objectentityops.getallobjectentities();              foreach (var graphnode in foundentities)             {                 var entityinformation = new objectentity()                 {                      id = graphnode.data.id,                      name = graphnode.data.name,                      datetimecreated = graphnode.data.datetimecreated,                      version = graphnode.data.version,                      status = graphnode.data.status,                      entitytype = graphnode.data.entitytype                 };                  objectentitylist.add(entityinformation);             }         }          public iqueryable<objectentity> items         {             { return objectentitylist.asqueryable<objectentity>(); }         }     } 

service class

public class objectentitiesservice : dataservice<objectentitydata>     {         // method called once initialize service-wide policies.         public static void initializeservice(dataserviceconfiguration config)         {             config.setentitysetaccessrule("items", entitysetrights.allread);              config.dataservicebehavior.maxprotocolversion = dataserviceprotocolversion.v3;         }     }
