Xamarin Form Picker - ItemDisplayBinding not working

Issue

Xamarin Form Picker - ItemDisplayBinding not working

I am trying to populate my Picker with a property of the objects in the ItemsSource, essentially exactly how it is documented here: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/picker/populating-itemssource#populating-a-picker-with-data-using-data-binding

Here is what I have so far:

Xaml

<ContentPage.BindingContext>
    <local:Model />
</ContentPage.BindingContext>

---

<Picker Title="Select a Profession" ItemsSource="{Binding Professions}" ItemDisplayBinding="{Binding Name}" />

Model - Binded

public List<Profession> Professions { get; set; }

Profession Object

public class Profession
{

    public string Name { get; set; }
}

So going by Microsoft's docs, the Name property should display, but it does not and in Visual Studio (For Mac - 2019), it doesn't event recognise Name as a property, just gives me the option of Professions again.

Am I doing anything obviously wrong?

Solution

I fixed this by changing List to an ObservableCollection. I was trying to populate my picker in an async method and an ObservableCollection implements the INotifyCollectionChangedInterface

Reference: ObservableCollection<> vs. List<>
