问题
I need to show a "welcome screen" (something like a license) when the user had first launched the application. This screen should be shown only once per user. Could someone guide me with this since I'm a beginner in windows development?
回答1:
You can use local storage or settings to store data on whether the "welcome screen" has been shown or not and use that to determine if the screen has to be shown on startup.

I don't know if there is something like LicenceInfo().
But for sure you can do it with IsolatedStorageSettings:
