❔ Questions about uno platform

After I learned how to build apps with wpf i want to lean how to build apps with uno platform. I know have the following questions: 1. How can I change the application icon of my uno app? 2. How can I customize the splash menu for wasm? 3. How can I write System specific xaml and c#? 4. How can I write seperate Ui pages for different systems? For example if the mobile apps should have a different ui than the wasm or windows apps 5. Where can i find the finished build applications to deliver?

I already tried to customize the splash screen by editing the AppManifest.js file, but it does not make a difference. I noticed that i can write anything in this file without getting an error and making a difference. i also tried to write system specific code this does not work:

using Microsoft.UI;

namespace MyUnoApp
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            string message = string.Empty;

#if NETFX_CORE
    message = "Hello from UWP World!";
#elif __ANDROID__
    message = "Hello from Android World!";
#elif __IOS__
    message = "Hello from iOS World!";
#elif __WASM__
    message = "Hello from Web Assembly World!";
#elif __MACOS__
    message = "Hello from MacOS World!";
#endif
            HelloTextBlock.Text = message;
        }
    }
}

using Microsoft.UI;

namespace MyUnoApp
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            string message = string.Empty;

#if NETFX_CORE
    message = "Hello from UWP World!";
#elif __ANDROID__
    message = "Hello from Android World!";
#elif __IOS__
    message = "Hello from iOS World!";
#elif __WASM__
    message = "Hello from Web Assembly World!";
#elif __MACOS__
    message = "Hello from MacOS World!";
#endif
            HelloTextBlock.Text = message;
        }
    }
}

and here only the windows part worked:
