I have a relational database (MS Sql Server):
State (1) <----> (*) City
It is mapped with EF4 and provided by a WCF Ria Service.
The Problem is, that I don't want to load the whole bunch of State/City data.(performance reason)
I only want to load the cities of the selected state. (lazy loading)
I am not very used with SL4 and Caliburn, so I think the performance is better this way, don't you think so?
If you can tell me a better, easier way with a nicer user experience, I am looking forward for new ideas.
