これが私のコードです。 

    private IHelloWorld ChannelFactoryWebService()
        {
            ServiceEndpoint tcpEndPoint = new ServiceEndpoint(
                                                ContractDescription.GetContract(typeof(IHelloWorld)),
                                                new NetTcpBinding(),
                                                new EndpointAddress("net.tcp://myserver/CultureTest/Service.svc"));

        ChannelFactory<IHelloWorld> factory = new ChannelFactory<IHelloWorld>(tcpEndPoint);
        factory.Endpoint.Behaviors.Add(new CultureBehaviour());

        return factory.CreateChannel();
    }


    [TestMethod]  <-------------- FAILING TEST ----
    public void ChangingCultureWASViaEndPointTest()

        Thread.CurrentThread.CurrentCulture = cultureInfo;

        client.Hello();
        string culture = client.HelloCulture();

        Assert.AreEqual("ar-SA", culture);  <--- fails here.. I get en-US for culture

    }

サービスのホスティングサイトのWeb構成は次のようになります。

  <endpointBehaviors>
    <behavior name="Default">
      <CultureExtension/>
    </behavior>
  </endpointBehaviors>

  <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

<extensions>
  <behaviorExtensions>
    <add name="CultureExtension" type="Extension.CultureBehaviorExtension, Extension, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

私の質問は、次のコード内で、Webサイトによってホストされているサービスを実行すると、サービスのHelloメソッド内でar-SAのカルチャ値を取得できないことです。ここで質問を明確にするために最善を尽くしました。他に何を明確にする必要があるか教えてください。

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, IncludeExceptionDetailInFaults = true)]
public class Server : IHelloWorld
{
    #region IHelloWorld Members

    public void Hello()
    {
    <--- problem here unable to get culture value of ar-SA here --->
        Console.WriteLine(string.Format("Hello world from the server in culture {0}", Thread.CurrentThread.CurrentCulture.Name));
    }

    public string HelloCulture()
    {

        string cultureName = Thread.CurrentThread.CurrentCulture.Name;
        Console.WriteLine("**************************hello**********************************");
        Console.WriteLine(cultureName);
        return cultureName;
    }

    #endregion
}

その特定のコードが機能しない理由は実際には答えではありませんが、カルチャ文字列を送信してWCFサービスのメソッドに設定しないのはなぜですか？

これが通常の方法です。認証されたユーザーの場合は、ユーザーに保存するだけで、コンピューターの構成に関係なく任意の言語に切り替えることができます。
