Type Parameters

If you don't have preexisting collection classes and need to create your own, the best choice is to use the built-in LiveLinq collection class IndexedCollection<T>. It is specifically optimized for LiveLinq use.

Usually, the element class T must implement the property change notification interface INotifyPropertyChanged. The easiest way to implement INotifyPropertyChanged is to derive the element class from IndexableObject.

In rare cases where implementing INotifyPropertyChanged is impossible, a custom PropertyChangeListener<(Of <(<'T>)>)> can be provided instead.

For details, see Using the built-in collection class IndexedCollection(T) (LiveLinq to Objects).

For alternative options in LiveLinq to Objects, see LiveLinq to Objects: IndexedCollection(T) and other collection classes

The IndexedCollection<T> class is not needed in LiveLinq to DataSet and LiveLinq to XML, because in those cases LiveLinq works with collections that already exist in ADO.NET and XML.
