I get exception "An exception of type 'System.ArgumentNullException' occurred in Xamarin.Forms.Platform.UAP.dll but was not handled in user code
Additional information: Value cannot be null." in MainPage.xaml.cs. How this fix?
public sealed partial class MainPage : WindowsPage
{
public MainPage()
{
this.InitializeComponent();
var start = Mvx.Resolve<MvvmCross.Core.ViewModels.IMvxAppStart>();
start.Start();
var presenter = Mvx.Resolve<IMvxViewPresenter>() as MvxFormsWindowsUWPPagePresenter;
LoadApplication(presenter.MvxFormsApp);
}
