How do you expand navigation properties of an entity through a service reference when you have a lot (20 in this case) of navigation properties to expand? I am executing the following code:
var result = MyEntities.Sample.Expand("Collector,Container,Coordinates...")
this results in the following URI:
http://192.168.0.196/Service.svc/Sample?$expand=Collector,Container,Coordinates,DispositionRequest,Employee,EstimatedSampleVolume,Facility,PreparationSize,Priority,Product,SourceLocation,SampleClassification,Unit,Vendor,Unit,WorkOrder,SampleType,Subject,Site,State
The error I am getting is:
$expand does not support '19' properties expanded simultaneously on the same segment.
It looks like no more than 13 simultaneously expanded properties is not currently supported in the OData protocol.
