WCF服务的身份验证不是使用SetAuthCookie和一个完整的.net客户端来维护的，而是使用silverlight

我已经设置了一个启用了表单身份验证和AspNetCompatibility的站点。实际的客户端是一个silverlight应用程序，并且工作得很好，但是我想使用normal .net单独对应用程序进行单元测试，以测试服务(对于没有副作用的方法的实时系统)。然而，当我停止使用Silverlight并开始使用完整的。net时，它不会保持身份验证

在web服务中，我有:

[OperationContract]
public bool Login(string Username, string Password, bool isPersistent)
{
    if (Membership.ValidateUser(Username, Password))
    {
        FormsAuthentication.SetAuthCookie(Username, isPersistent);
        return true;
    }
    else
    {
        return false;
    }
}
[OperationContract]
public bool IsLoggedIn()
{
    return HttpContext.Current.User.Identity.IsAuthenticated;
}

然后在客户端的测试方法中，我这样调用它:

Assert.IsTrue(Client.Login("MyUsername","MyPassword", true));
Assert.IsTrue(Client.IsLoggedIn());

客户端是.net自动生成的servicerreference客户端的一个实例。第一个断言通过了，但第二个断言失败了，即从一个方法调用到下一个方法调用，它停止登录。在silverlight应用程序中，类似的方法将通过。

我怎样才能使正常的。net行为正确的silverlight将?有没有更好的方法来配置完整的。net客户端/服务?

请求的附加信息

<services>
  <service behaviorConfiguration="MyBehaviour" name="SSCCMembership.Web.Services.LoginService">
    <endpoint address="" binding="customBinding" bindingConfiguration="customBindingBinary"
      contract="SSCCMembership.Web.Services.LoginService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<bindings>
  <customBinding>
    <binding name="customBindingBinary">
      <binaryMessageEncoding />
      <httpTransport />
    </binding>
  </customBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="MyBehaviour">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

身份验证配置:

<authentication mode="Forms" />
<membership defaultProvider="OdbcProvider">
  <providers>
    <clear />
    <add name="OdbcProvider" type="SSCCMembership.Web.SimpleMembershipProvider" applicationName="/SSCCMembership" requiresUniqueEmail="false" connectionStringName="mainConn" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" writeExceptionsToEventLog="true" />
  </providers>
</membership>

然后使用以下代码在WPF

public static T LoadService<T>(string URI, Func<CustomBinding, EndpointAddress, T> F)
{
    try
    {
        Uri U = new Uri(new Uri(Root), URI);
        BinaryMessageEncodingBindingElement binary = new BinaryMessageEncodingBindingElement();
        HttpTransportBindingElement transport;
        if (U.Scheme == "http")
            transport = new HttpTransportBindingElement();
        else if (U.Scheme == "https")
            transport = new HttpsTransportBindingElement();
        else
            throw new Exception(U.Scheme + " is not a recognised URI scheme");
        transport.MaxBufferSize = int.MaxValue;
        transport.MaxReceivedMessageSize = transport.MaxBufferSize;
        transport.AllowCookies = true;
        CustomBinding binding;
        binding = new CustomBinding(binary, transport);

        EndpointAddress address = new EndpointAddress(U);
        return F(binding, address);
    }
    catch (Exception)
    {
        return default(T);
    }
}

我称之为:

var Client = LoadService(ServiceLocation, (b,e)=>new LoginServiceClient(b,e));
