I have this GREAT WCF service that returns Data from EF.
public class HistoryDataService : DataService<HistoryEntities>
{
#region Public Methods
public static void InitializeService(DataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;
}
[WebGet]
public IQueryable<History> GetHistoriesById(int recordId)
{
return CurrentDataSource.Histories.Where(d => d.RecordId == recordId);
}
#endregion
}
I have other services that I added something like:
[WebGet(UriTemplate = "eventdetails/{id}", ResponseFormat = WebMessageFormat.Json)]
to make it more of a traditional RESTful service, however, when I add it I get various errors like:
... both defines a ServiceContract and inherits a ServiceContract from type System.Data.Services.IRequestHandler.`
How do I add this property or is it even possible?
It would save you a lot of time to use WCF Data Services or OData as it is called. You'll get both JSON and XML output for your web service response. Your choice. : )
