We're trying to upgrade to the latest Csla 4.5 on .Net 4.0. We're still using remoting for the time being and will at some future point move to WCF, but for now remoting it is. I've hit a problem where the BinaryFormatter hangs when deserizlizing one of our types. The odd part is that it does work the first few times, it only fails after a few back and forths. So I'm trying to move us to the NetDataContractSerializer, which we'd use on WCF anyway.
My issue there is that immediately we get an exception (before any of the remoting even happens) when trying to serialize the very first type. It fails with a SerializationException: Type is not resolved for member "ABC" I've not been able to find any useful information, and its my understanding the NDCS should pretty much be a drop in replacement for BinaryFormatter and thus honor the Serializable / NonSerializable attributes.
This failure is happening just running our unit tests over remoting, both in R# and in the NUnit GUI. Here's a portion of the stack trace (omitted parts are our code / remoting proxy calling into serialize the object):

Any ideas?
