title: .Net 4.5 : Should I use IDataErrorInfo or INotifyDataErrorInfo?
body: <p>I used to use <code>IDataErrorInfo</code> in my MVVM/WPF applications. Now after <code>INotifyDataErrorInfo</code> is available in .Net 4.5 is it better to replace <code>IDataErrorInfo</code> or continue the old way using <code>IDataErrorInfo</code>?</p>
