Question

I’m having an issue with the following code:

    private void DataPortal_Fetch(TaskCriteria criteria)     {         using (var ctx = ContextManager<Gimli.Data.GimliDataContext>                     .GetManager(Database.ApplicationConnection, false))         {             this.RaiseListChangedEvents = false;             this.IsReadOnly = false;              IQueryable<Data.Task> query = ctx.DataContext.Tasks;              if (criteria.ReadyForPricing)             {                 query = query.Where(row => row.IsPriced != true);                 query = query.Where(row => row.Status == (int)TaskStatus.Closed);                 query = query.Where(row => row.InvoiceId == Guid.Empty);             }              if (criteria.ReadyForInvoicing)             {                 query = query.Where(row => row.IsPriced == true);                 query = query.Where(row => row.Status == (int)TaskStatus.Closed);                 query = query.Where(row => row.InvoiceId == Guid.Empty);             }              var data = query.Select(row => TaskInfo.FetchTaskInfo(row));              this.AddRange(data);              this.IsReadOnly = true;             this.RaiseListChangedEvents = true;         }     } 

My web application, when it calls this method, always hangs if I don’t comment out the following line:

query = query.Where(row => row.InvoiceId == Guid.Empty) 

Any idea why this would be happening?

Answer 1

The following code works … interestingly enough … any idea of why?

query = query.Where(row => row.InvoiceId == new Guid('00000000-0000-0000-0000-000000000000'));
