In WCF is there a way to set ServiceContract Namespace assembly-wide?

Question

In WCF land, you can specify a Namespace prefix for anything that has a [DataContract] like so:

[DataContract(Namespace="MyApp")] public class whatever...

However if you wanted to apply a common namespace to ALL data contracts assembly-wide, you can use the ContractNamespaceAttribute:

/* in AssemblyInfo.cs */
[assembly: ContractNamespace("MyApp", ClrNamespace = "MyApp")]

/* in whatever.cs */
[DataContract] public class whatever...

Thats great, works fine. Now over on the ServiceContract side, I can do the same Namespace setup on the service interface:

[ServiceContract(Namespace="MyApp")] public interface whateverService...

But is there something comparable to [assembly: ContractNamespace] that can be used to set the Namespace for all [ServiceContract]s? I'd really like to avoid having to set it manually for however many services, its nice having it in 1 place for the data contracts. Since there is an assembly level namespace attribute for the data contracts, i'd hope there is one for the service contracts too...

No, you cannot - you have to be very explicit in WCF and you have to explicitly set things like namespaces on each and every ServiceContract. I would probably even do it on each and every DataContract as well - just to be clear about what I am doing.

It's a good thing, though! Being explicit also makes your intentions clear - trust me, in a complex system, that helps !
