CRM 2011 - Activity Party and SerializationException in plugins

I was working with the requiredattendees on the appointment entity and ran into a miserable time with a serialization exception. Funny thing was the exception is only thrown when I registered my plugin as isolation (aka sandbox) mode. No one seemed to have a post on the exact same issue so here's how I solved it:


I found an article about it that suggested removing all references to the activityparty svcutil generated class: http://nicolagrillo.blogspot.ca/2012/01/crm-2011-activityparty.html

That did not work, but I have not tried completely removing all reference to the class in my assembly as that is an unrealistic solution in my situation.
My error from the server trace: important part extracted for visibility:
System.Runtime.Serialization.SerializationException: Element 'http://schemas.microsoft.com/xrm/2011/Contracts:Entity' contains data from a type that maps to the name 'MyNamespace:ActivityParty'. The deserializer has no knowledge of any type that maps to this name. Consider changing the implementation of the ResolveName method on your DataContractResolver to return a non-null value for name 'ActivityParty' and namespace 'MyNamespace'.

I am very curious why it fails in isolation mode and works in non isolation. I hope the stack trace triggers a thought from someone.

Ultimately it turns out you cannot use the early bound classes when you want to assign to the target entity when you are in this context. I still don't complete understand what the context is that causes this error, because I use early bound classes in sandboxed plugin steps all the time, often assigning them into the target entity input parameter.
