Implementing a demo using Validation in .NET FX 4.5

Question

I'm surprised that MS has implemented a new feature: Validation with INotifyDataErrorInfo

I have heard so improvement in this validation class, so I'd like to implement this one using WPF, but in MSDN I can't find an official sample demo to understand this interface.

If you have one, can provided me? Thanks in advance
