Description
The validation section only mentions `IDataErrorInfo`, it should additionally or exclusively recommend its successor `INotifyDataErrorInfo`.
I had heard a recommendation of `INotifyDataErrorInfo` elsewhere but after reading this article i got the false impression that it isn't supported in WPF and wasted some time implementing `IDataErrorInfo` on my Viewmodels. Only when searching for more tutorials later I found one using `INotifyDataErrorInfo` and rewrote my code.
