Hello, Soliciting feedback/options/comments regarding a "best" pattern to use for reference data in my services. What do I mean by reference data? Let's use Northwind as an example. An Order is related to a Customer in the database. When I implement my Orders Service, in some cases I'll want the reference a "full" Customer from an O...
Is it possible to create a library that can be consumed from .Net 2.0 and also allows .Net 3.0+ consumers to benefit from DataContracts if they wish? I don't see any technical obstacle for this other than the library that contains the different DataContract related attributes is a .Net 3.0 library. Can these attributes be implemented ma...
I'm trying to take a datacontract object that I received on the server, do some manipulation on it and then return an upcasted version of it however it doesn't seem to be working.

How bad is it? I have read countless articles and never created abstract DataContracts with behavior before, but it seems that doing so will solve an issue I am having that will prevent me from creating factories everywhere to determine a subclass implementation. My question is, will I be punished if I decide to add behavior to my data c...
Using VS 2008 & .NET 3.5 SP1: I am using WCF to allow clients to connect to a service that reads and writes database entries using Entity Framework. By default the entities that are generated automatically from the database have the DataContract attribute applied. Unfortunately many of the fields are exposed are not meant for consumpt...
This is more of a philosophical/best-practice sort of question rather than a technical problem. Are there any strong arguments against writing a DataContract class with methods that are to be used server-side only? Or what about additional properties that are not decorated with the DataMember attribute? For example: [DataContract] pub...
