Question

I am developing an app using Prism and Xamarin Forms. I used Prism template to create the project in Visual Studio 2017 community edition.

Here is the app.cs page

protected override void OnInitialized()
{
    InitializeComponent();

    NavigationService.NavigateAsync("BasePage");
}

protected override void RegisterTypes()
{
    Container.RegisterTypeForNavigation<BasePage>();
    Container.RegisterTypeForNavigation<MainNavigationPage>();
    Container.RegisterTypeForNavigation<MilkPurchasePage>();
    Container.RegisterTypeForNavigation<TruckSheetPage>();
    Container.RegisterTypeForNavigation<LocalSalePage>();
    Container.RegisterTypeForNavigation<MembersPage>();
}

Now BasePage contains Hamburger menu and from there it will navigate to MilkPurchasePage

Now everything works when I run the project on mobile but once I close the app I get

Unfortunately , MilkApp.Droid has stopped.

I only added user interface. No background code has been added other than navigation.

I tried to debug bug I am unable to get it in visual studio. I checked all errors in Error Settings too. But still I am unable to solve it.

Why I am getting this ?

这实际上是Xamarin.Forms的一个问题。他们过去修正了这个问题，但看起来他们可能已经倒退了。您可以通过创建标准XF应用程序轻松地重现这一点。您应该将此作为错误提交给Xamarin。
