Windows store apps - detect first launch of the app

Question

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?

Answer 1

您可以使用本地存储或设置来存储有关是否显示“欢迎屏幕”的数据，并使用该信息确定启动时是否必须显示该屏幕。

Answer 2

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