We have a lot of classes where the members is decorated with [DataMember]. It would be very nice if there was a AutoWcfMap in BsonClassMap that works as AutoMap but that looks at [DataMember] attributes instead.

Example:
BsonClassMap.RegisterClassMap<MyClass>(cm => cm.AutoWcfMap());

Would iterate over all members (public/private fields/properties) and see look for the DataMember attribute and call SetElementName, SetOrder, SetDefaultValue etc.

If the type have a member-type that is marked with the DataContract attribute and it is not currently a part of the registered types it should automatically map it too.
