csharp
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        Person person = new Person();
        person.Name = "John Doe";
        this.DataContext = person;
    }
}
public class Person : INotifyPropertyChanged
{
    private string name;
    public string Name
    {
        get { return name; }
        set
        {
            if (name != value)
            {
                name = value;
                OnPropertyChanged(nameof(Name));
            }
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
