c# - delegates across diffferent machines -

-

it seems should dead easy, couldn't find in google on it:
have video store server, , has multiple client applications, installed on users' machines, communicating via (let's say) web services.
when dvd returned, i'd able notify useres have been waiting dvd.

when dealing single application, that's no problem using delegates.
question is- can approach work remote clients well?

you can use duplex wcf service that.

but if dvd handling service user doesn't need notified immediately, recommend solution users' clients poll server every 10 minutes. far more simple implement.
