NetDataContractSerializer equivalent for Silverlight?

Has anyone developed or know of a place where I could find a Silverlight implementation of NetDataContractSerializer?

This WCF and Silverlight Comparison states that Silverlight does not ship with an implementation of NetDataContractSerializer.

I'm hoping to avoid developing one myself.

Thanks!

• I might be wrong, but I think the Silverlight version of CSLA includes some form of binary serializer. It's not compatible with NetDataContractSerializer I think, so you'll need to use it on both the server and client (CSLA comes in a Windows flavour too).
