I'm trying to get a list of entities from a WCF service, the problem I'm experiencing is that we have some bad latency on the network and so the data takes a considerable amount of time to get to my client. The idea I have is to find a way to get the first 1000 and just push those to the UI while I'm waiting for the next ones to arrive.

I guess it would be like paging but I just want to page the full set in the WCF layer rather that get one page at a time from the db
干杯
