I tried with the code below this text to open from my own developed Windows Phone 8.1 app others Windows Phone Apps without success. When I push the buttonNavigator button the phones freezes or sometimes nothing happens. It is possible to open other Windows Phone 8.1 apps within your own developed Windows Phone 8.1 application?
HTML Code:
Private Async Sub buttonNavigator_Click(sender As Object, e As RoutedEventArgs) Handles buttonNavigator.Click
Await Windows.System.Launcher.LaunchUriAsync(New System.Uri(Calendar))
End Sub
