//KeyedCollection keeps an internal lookup dictionary for better performance.
//With normal implementations of an observable KeyedCollection, when used for
//data bindings in WPF, once the key of the item is changed with bindings, the
//corresponding key internal dictionary is not changed, which leads to hidden
//problems when the dictionary is used.
//Below is a custom implementation of KeyedCollection to solve that problem.
