In my current WPF project, people are widely using observable container like ObservableCollection<T>. The other day someone whinged why there is no observable dictionary like ObservableDictionary<T>??
All right, I googled and then found an implementation. It greatly implemented so many interfaces...oh!! I even don't notice some of them when I was using containers!
As a lazy and stupid man, I tailored it and worked out a simple version by inheriting dictionary directly. Here coming code.
