When you bind to a property in QML, it is assumed you want QML to also "watch" the property for changes. It can't do that if it has no signal to listen to for changes.

[NotifySignal] // This is the important part
public string TestProperty
{
    get => _testProperty;
    set => this.SetProperty(ref _testProperty, value);
}
