it helps some times Hi there ive been wrecking my head all night and I know I'm missing something simple. Please Help! , Solved! For some reason it does not work with a foreach loop.
code :
 for (int i = 1; i <= 8; i++)
            {


                if (!(TakenSlots.Contains(i)))
                {
                    await DisplayAlert("Alert", "does not contain " + i, "Ok");
                }
                else
                {
                    await DisplayAlert("Alert", "does contain " + i, "Ok");
                }


            }

seems to work fine I want to create function for generate data to show in treeview. But have some problem with code below, please help me. , You can't. Imagine you have this method:
code :
void foo(ObservableCollection<object> collection) {
    collection.Add(new Tiger());
}
var ints = new ObservableCollection<int>();
foo(ints);
public class DataControl {
    public string Type { get; set; }
    public INotifyCollectionChanged Data;

    public DataControl(string type, INotifyCollectionChanged data) {
        Type = type;
        Data = data;
    }
}
void OnObservedCollectionChanged(object sender, NotifyCollectionChangedEventArgs e) {
    if (e.Action == NotifyCollectionChangedAction.Add)
        AddNewItemsToTreeView(e.NewItems); // NewItems are all "untyped" object
}

it fixes the issue You can use ToDictionary() like this:
code :
ObservableCollection<KeyValuePair<string, object>> KeyValueCollection =
          new ObservableCollection<KeyValuePair<string, object>>(collection.ToDictionary(
              entry => t.Name, 
              entry => (object)entry));
