ListView ItemTemplate Binding

[TigerMax]

Good evening!
I am new to Uno Framework and came from adjacent field in development.
I seem to fail to grasp something basic in regards to binding.
I have a simplified test collection in my Model:

public ObservableCollection<TestData> testCollection = new ObservableCollection<TestData> { new TestData("1","1"), new TestData("2","2") };

public record TestData
{
    public string name;
    public string description;

    public TestData(string name, string description)
    {
        this.name = name;
        this.description = description;
    }
}

I want to display this data in ListView...

ListView declaration:

MainMenuPage.cs

this.DataContext<MainMenuViewModel>((page, vm) => page
    .NavigationCacheMode(NavigationCacheMode.Required)
    .Background(Theme.Brushes.Background.Default)
    .HorizontalAlignment(HorizontalAlignment.Stretch)
    .Height(App.appHeight)
    .Content(
     new StackPanel()
        .Children(
        new ListView()
        .Height(App.appHeight - 100)
        .HorizontalAlignment(HorizontalAlignment.Stretch)
        .ItemsSource(() => vm.testCollection)
        .ItemTemplate<TestData>((item) => ShowTestConnection1(item)),
       <...>
    ));

I have two test methods.
The first one...

MainMenuPage.cs

    public UIElement ShowTestConnection1(TestData testRecord)
    {
        return new Frame().Height(75).Background(Colors.Green).
        Content(
        new TextBlock().Text(() => testRecord)
        );
    }

... returns as expected:

TestData {name = 1, description = 1}
TestData  {name = 2, description = 2}

But the second one...

MainMenuPage.cs

    public UIElement ShowTestConnection2(TestData testRecord)
    {
        return new Frame().Height(75).Background(Colors.Green).
        Content(
        new TextBlock().Text(() => testRecord.name)
        );
    }

... returns nothing!

Closest info i could find was this.
Tried copying 1 to 1. I fail to see the difference, but it doesnt work for me.

UNO documentation was also no help.

What am i doing wrong?
Where can i find more code examples in C# Markup? Everything i see is in XAML.
I can guess the way to convert one to another but it is difficult for newbie.

Thank you in advance!

As it always happens, you bang your head for 6 hours and figure everyting out right after you ask a question.
For future newbies:
My mistake wasn't in declaration of my list, but in a data class!
I forgot to add getters to my fields.
