Forum Cross Platform with Xamarin

Windows Phone LaunchFileAsync Error

Hi,

I am trying to open a PDF in from a Windows Phone PhoneApplicationPage with Windows.System.Launcher.LaunchFileAsync(file);.
But everytime I do so the App crashes with NullReferenceException in Xamarin.Forms.Platform.WinPhone.FormsApplicationPage.OnDeactivated(Object sender, DeactivatedEventArgs e).
Does anyone know what the problem is or the better how to solve it?

Best Regards
Oliver
