' I watched Karl's video about validation with custom rules, and wondered
' why Silverlight, ASP.NET and ASP.NET MVC had DataAnnotations, and
' WPF only had IDataErrorInfo. So I thought of using EF4 as the model,
' and generating a metadata class like in RIA, MVC, etc for WPF and a
' inheritable generic class to convert the validations between IDataErrorInfo
' and the DataAnnotation attributes. 
'
' This way validation can happen the same way for each type of client!
'
' Let me know what you think please?
