I was looking first for about how to implemented in Silverlight (I can imagine that it's implemented in the same way), but I can't find a compact demo of this new interface. Is it possible to show how can I use it?
我首先在寻找如何在 Silverlight 中实现（我可以想象它是以相同的方式实现的），但是我找不到这个新界面的紧凑演示。是否可以展示我如何使用它？
I really want to find a small demo to understand it
真想找个小demo了解一下

Beside the very detailed description on MSDN about the Silverlight version of INotifyDataErrorInfo
除了MSDN上关于INotifyDataErrorInfo的Silverlight版本的非常详细的描述
There are already some blog posts with samples how to use/implement it in WPF 4.5:
已经有一些博客文章包含如何在 WPF 4.5 中使用/实现它的示例：
- WPF 4.5 – Asynchronous validation (original link no longer working)Wayback Link
- WPF 4.5 – Part 1 : Asynchronous data validation(the author has a nice seriesabout the new fetaures in WPF 4.5)
- WPF 4.5 - 异步验证（原始链接不再有效）Wayback Link
- WPF 4.5 – 第 1 部分：异步数据验证（作者有一个关于 WPF 4.5 中新特性的不错的系列）

The PRISM libraryhas a very good example implementation in the MVVM RI sample, the class named DomainObjectimplements both INotifyPropertyChanged and INotifyDataErrorInfo.
该PRISM库有MVVM RI样品中一个很好的例子实施，命名类domainObject的同时实现了INotifyPropertyChanged的和INotifyDataErrorInfo。
It is a SL version but it now compiles with .NET 4.5
它是一个 SL 版本，但现在可以使用 .NET 4.5 进行编译
