Question

Hello Everyone,

 

I have two Register and Login .xaml page for windows application wpf c#.net. And the start up page is,

StartupUri="Register.xaml">

The problem is, after install .exe in any other local computers. Then 1st appear Register page after successfully registering, then show login page only. But the registration should happened 1st time only. Anytime after the application tries to run/open then show login page only?

 

Kindly guide me,
