Я работаю над проектом .NET MAUI и столкнулся со следующей ошибкой:

Код: Выделить всё

[0:] Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics: Warning: 'IsAudioEnabled' property not found on 'TTIG02_Controller.Components.ToggleSettingsItem', target property: 'TTIG02_Controller.Components.ToggleSettingsItem.IsToggled'
[0:] Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics: Warning: 'IsNotificationEnabled' property not found on 'TTIG02_Controller.Components.ToggleSettingsItem', target property: 'TTIG02_Controller.Components.ToggleSettingsItem.IsToggled'

Это соответствующие части кода:

{

if(string.IsNullOrWhiteSpace(tsi.Key)) return;
if(BindingContext is not SettingsPageViewModel vm) return;

Log.Verbose("SettingsPage.ToggleSettingsItem_ToggleChanged: {Key} toggled to {IsToggled}", tsi.Key, e.Value);

}
}

public event PropertyChangedEventHandler? PropertyChanged;

protected virtual void OnPropertyChanged(string propertyName)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
}

Следуя рекомендациям по похожим сообщениям, которые я уже пробовал:

• Удалить x:DataType
• Установить xmlns:local
• Удалить BindingContext = this; из ToggleSettingsItem
  < li>Doing IsToggled="{Binding" Source={x:Reference SettingsPage}, Path=BindingContext.IsNotificationEnabled}"

Может ли кто-нибудь помочь мне выяснить, что вызывает эту проблему?

Спасибо!
