Is this possible to generate self expiring download link in C# - WPF? -

-

i'm working on c# - wpf project zune , want sell digital goods apps want create disposable link files in server , after successful payment in application, generate new download link requested file. link should expire after downloaded.

is possible do? if yes how can it?

sir or ma'am,

i think design bit wrong. said you’re working on zune'esk project. means should able forego use of links , use web services wcf or soap. change design , make wpf project call web service. once app download content, let call api , mark item downloaded in persistency store , call day. can set “issued” date time stamp on token expires in 1 day. way if user never comes item, auto-expire.

once working, can go ahead , add authentication , validation structure ensures 1 user download. there many authentication frameworks choose windows, username/password, ect.
