For large servers clients can optionally rely on large network-message sizes or result-paging or a combination of both to retrieve a large number of messages. Maximum network-message size is straight-forward and controlled by ConnectionProperties.MaxReceivedMessageSize - it must be matched on both client and server.

Result-paging enables large result sets to be retrieved across multiple server requests with timing and size controlled by the client. The number of results retrieved per request is controlled via the query's PageSize property. To utilize result-paging, specify a non-zero PageSize and continue calling the same query while the return code is true to retrieve all results from a server. To protect the server and limit excessive server-memory utilization initiating a second query without first retrieving all results for a first query generates a fault.
