Method 'Boolean Contains..' has no supported translation to SQL

Question

i have this in my query:

var results = (from urls in _context.Urls
               join documents in _context.Documents on urls.UrlId equals documents.Documen         


        

Answer 1

An interesting fact about this is that I get the following error when running in .NET 4.0 on my development machine:

"Method 'Boolean Contains(Int32)' has no supported translation to SQL."

But it runs just fine in the production environment that utilizes .NET 3.5.

I am guessing that it is the difference in versions between the two environments. However, it is a fact that I get the error on my development machine, but the queries DO RUN on the production environment and the LINQ query does contain the following code

var resultParts = (
                from l in tempDc.LineItems
                from wo in tempDc.WorkOrders
                where l.WorkOrderNumber == wo.WorkOrderNumber &&
                    l.OrderID == wo.OrderID &&
                    workOrderSerialNumbers.Contains(wo.SerialNumber) &&
                    l.Part.PartTypeID == (int)PartTypes.InventoryPart
                orderby l.OrderID_WO, l.WorkOrderNumber
                select new PickReportPartDto()
                {...

Where 'workOrderSerialNumbers is a List.
