Assembly ContractNamespace doesn't seem to work? - wcf

Question

I don't want to set the namespace for every single one of my data contracts so I decided to use the ContractNamespace attribute in the AssemblyInfo.cs file of the project where my DataContracts reside. Here is the entry
[assembly: ContractNamespace("http://www.mycompany.com/MyProject/", ClrNamespace = "Company.Project.Client.Entities")]
This does nothing. It seems I HAVE to specify the namespace on all the data contracts like so:
[DataContract(Namespace = "http://www.mycompany.com/MyProject/")]
..and yes, I have verified that my DataContracts are in fact in the specified ClrNamespace. Why doesn't this work? I'm using .net 4.5. Thanks.
Update: Here is the WSDL generated when I use explicit namespacing on the contract:
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:i0="http://www.company.com/Project/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://tempuri.org/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" name="AccountService" targetNamespace="http://tempuri.org/">

Answer 1

Ok, I had two issues here. First was a typo in one of the ClrNamespace that I can't believe took me so long to notice. The second was that my Contracts were in a project, lets say Company.Project.Contracts. That project had a few folders, lets say Data and Service (for data and service contracts), and had some contracts in the namespace Company.Project.Contracts. Thus, in my AssemblyInfo.cs file, I had to have MULTIPLE ContractNamespace attributes like so:
[assembly: ContractNamespace("http://www.company.com/Project/", ClrNamespace = "Company.Project.Business.Contracts")]
[assembly: ContractNamespace("http://www.company.com/Project/", ClrNamespace = "Company.Project.Business.Contracts.Service")]
[assembly: ContractNamespace("http://www.company.com/Project/", ClrNamespace = "Company.Project.Business.Contracts.Data")]
Also, #nodots, thanks for the pointers/help.

Answer 2

The ContractNamespace only applies to data contracts. You still have to set the service namespace on [ServiceContract].
The line
<xsd:import schemaLocation="http://my.server.local/Project/Account/AccountService.svc?xsd=xsd2" namespace="http://www.company.com/Project/"/>
in your WSDL indicates the ContractNamespace attribute does work.
