WPF应用和ClickOnce的试用期

We're deploying .NET WPF app to beta-testers using ClickOnce. We want to set a expiration date after which the app doesn't open anymore. Fixed date or x days from the first installation are both ok. After the trial we ask the users to unistall the app from their computers. In case they don't do so, we want that the app doesn't open anymore.We're deploying .NET WPF app to beta-testers us
