Windows.UI.Xaml.DependencyObjectCollection

-description

Implements a practical collection class that can contain DependencyObject items.

-remarks

The purpose of the DependencyObjectCollection class is mainly to support the tooling and portability of behaviors. Behaviors are a technique for defining certain basic interactions of a UI element entirely in XAML, without requiring an event handler and code-behind.

If you're interested in implementing a business object class that supports collection-changed notifications you should use ObservableCollection or one of the interface patterns that supports changed events. For more info see Data binding in depth.

Enumerating the collection in C# or Microsoft Visual Basic

A DependencyObjectCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<DependencyObject> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a DependencyObject constraint.
