client/server implementation

[Chris Bordeman]

Hi all. I need to create an app that runs both at individual client PCs, on
the client's on-site server, and on a main server depending on network
connectivity, probably w/ database replication.

What technologies should I use so that the software running on all three
locations looks the same, scales from the single PC to the site server, to a
master off-site server, WITHOUT writing different software for each "tier?"
Moreover, the # of tiers could increase.

I'm guessing WPF and SQL Express / Server to start...

Hello Chris,

You forgot the WCF, which provide abstraction layer between presentation
and data.
It's that clue which helpÙ you to make physical data location really transparent

You need WCF.

It is an abstract model, that puts you "above" any one communication
methodology.

I suggest Juval Lowry's book on programming WCF services.
