Question: Can anyone tell me the difference between these 3 IDs?

I want to identify a particular installation (per purchase/device and not counting minor updates) of my win8 app, which of them will best fit my need?

Answer: 
```
TextBox tb = new TextBox();
tb.Name = "contentBox";
tb.AcceptsReturn = true;
Binding b = new Binding("Content");
b.Mode = BindingMode.TwoWay;
b.Source = this; // set you DataContext here
tb.SetBinding(TextBlock.TextProperty, b);

```
```
        Binding binding = new Binding();
        binding.Mode = BindingMode.TwoWay;
        binding.Path = new PropertyPath("Content"); //Name of the property in Datacontext
        BindingOperations.SetBinding(contentBox,TextBox.TextProperty , binding);

```
