Since I have to define my fault details with DataContractSerializer attributes for now (I hope it's only for now anyway), I was looking at how to translate a property that was previously serialized by the XmlSerializer using XmlArrayAttribute and XmlArrayItemAttribute. Well, I figured out pretty quick there was no equivalent, found CollectionDataContractAttribute, but thought "noooo, this can't be the only way... can it?". Unfortunately a quick search revealed this post by Christian Weyer that confirmed my fears. Why oh why do I have to go writing a whole new collection class now just to decorate it with attributes when I could decorate the member itself?
Argh... there's nothing more frustrating than seeing an API try to re-invent the wheel and end up with something that is worse off than what we have today. :(
