How to implement INotifyDataErrorInfo in WPF 4.5? [closed]

Answer 1

The PRISM library has a very good example implementation in the MVVM RI sample, the class named DomainObject implements both INotifyPropertyChanged and INotifyDataErrorInfo.

It is a SL version but it now compiles with .NET 4.5

Answer 2

Beside the very detailed description on MSDN about the Silverlight version of INotifyDataErrorInfo

There are already some blog posts with samples how to use/implement it in WPF 4.5:
