public static class DelayedBinding

The XAML engine applies its bindings in a delayed manner where bindings are only applied when a control has finished initializing. This is done because applying bindings as soon as controls are created means that long-form bindings (i.e. bindings that don't use the `{Binding}` markup extension but instead use `<Binding>`) don't work, as the binding is applied to the property before the properties on the `Binding` object are set. Looking at WPF it uses a similar mechanism for bindings that come from XAML.
