Am I supposed to expand on this class by hand and code all the methods for this "Page" class? Is there a tutorial that shows how to do this?

<Grid x:Name="LayoutRoot" />

this.LayoutRoot.Background = new SolidColorBursh(Colors.Red);

public class Field : INotifyPropertyChanged
  {
      private string _value;
      public string Value
      {
          get {return _value;}
          set
          {
              _value = value;
              NotifyPropertyChanged("Value");
          }

Maybe I should add something to resources ?

private Field _field;
private void SetContext()
{
  _field = new Field();
  DataContext = Field;
}

No. Drop the DataContext from your XAML

LayoutRoot.DataContext = this;

public Field Val { get; set; }
<TextBlock Grid.Row="1" Name="txtTest"  Text="{Binding Val.Value}"/>
