You are implementing a WCF Data Service client application. You generate WCF Data Service client library classes, including a class that extends DataServiceContext named NorthwindEntities. NorthwindEntities includes a property named Orders that gives Order entities. You need to retrieve Order entities and access the HTTP response code if the request fails.

What should you do?

To retrieve entities and the HTTP response, query the Orders collection using a QueryOperationResponse. Check the returned QueryOperationResponse object's Status property. This property gives the HTTP response.

The DataServiceRequestException exception will be thrown only if the entities cannot be retrieved. You cannot use this exception to retrieve the HTTP response code unless an error occurs.
