Good morning
I am creating an application in WCF and would like help or guidance at the following point: I need to make the app available for anyone to download and test it, type a test for 30 days and then restrict access.
How can I create such a mechanism in WPF?
Thank you in advance for your attention and help.
I think you would need the following:
If you do it by date, you should be very concerned about the restriction, because if the user changes the date it can give a problem, and if you get the date of a WebService you will have to be logged in.
I did a similar thing a while back, but I did not care much about date tracking, I did the following:
The user can use for 30 days or X Uses (initializations).
When I start the system, I check if the date has already passed, if it has not passed if the usage has passed. Except the uses in a counter in a localDB along with the information of the app.
This was the best, fastest way I found to do something similar to what you're looking for.
