Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
DataMember extended to DataAnnotation
It would also be nice if DataMember could integrate some concepts of the DataAnnotation.
It would improve performance since validation would happen during serialization process and enable generation of proxies that integrate such concepts. Note that Xml Schema already support such concepts.
