c# - Determine Client version of Application on Startup -

problem:

we have c# application, .net 3.5 updated manually on client computers. don't ask, can't one-click deploys.

when new build created , client has not been updated, alert client (on start-up) application out of date , new build must obtained before proceeding.

i interested in approaches others may have used solve same problem (restricting clients using old builds)

thanks - glenn

you need create web service return current application version. service must installed available clients call.

then need add call service , check running application version against version service.
