How to do a simple DataBind

Hi,

I would like to bind an object with its properties to a StackLayout inside my ContentPage.
So basically I have an object with two properties Name and Lastname that is a class property inside my Page.xaml.cs:

I tried different ways to bind it, but all causes the application to just close/crash. So lets say this is my incorrect data-bind implementation:

//Stacklayout inside XAML
<StackLayout x:Name="TestLayout" BindingContext="{Data}">
    <Label Text="{Binding Name}"/>
    <Label Text="{Binding Lastname}"/>
</StackLayout>

//My object
public class MyObject : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    public string Name
    {
        get
        {
            return Name;
        }
        set
        {
            Name = value;
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(nameof(Name)));
            }
        }
    }
    public string Lastname
    {
        get
        {
            return Lastname;
        }
        set
        {
            Lastname = value;
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(nameof(Lastname)));
            }
        }
    }

    public MyObject(string name, string lastname)
    {
        Name = name;
        Lastname = lastname;
    }
}

//My page
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MyPage : ContentPage
{
    private MyObject Data;
    public Unloading(string env, string username, string name, string call, PageOptions options)
    {
        InitializeComponent();
        Data = new MyObject("John", "Doe");
    }
}

How do I need to set BindingContext in order for it to work?
