Application works in Debug build but crashes in Release build when binding ImmutableArray to ItemsSource with x:Static

[andrekoehler]

Description

The application works in Debug build but crashes in Release build as soon as navigating to the XAML that uses x:Static to bind Picker.ItemsSource to an ImmutableArray.

Steps to Reproduce

1. Create a new MAUI app
2. Add SomeViewModel.cs:

namespace MauiApp1;
public class SomeViewModel
{
    public System.Collections.Immutable.ImmutableArray<string> Letters => ["A", "B", "C"];
    public static System.Collections.Immutable.ImmutableArray<string> StaticLetters => ["A", "B", "C"];
}

3. Add this to MainPage.xaml:

        <!-- crashes only in Release build -->
        <Picker ItemsSource="{x:Static local:SomeViewModel.StaticLetters}" />

        <!-- works in Debug and Release build -->
        <!--<Picker ItemsSource="{Binding Letters}" />-->

4. Select Release build and run the app on Windows Machine
5. The app will immediately crash if the picker is on the MainPage. In my actual app it crashes as soon as I enter the page with the picker.

Did you find any workaround?

Do not use a static property with x:Static, instead use a non-static property with Binding.
