我有一个silverlight项目。同一解决方案中有2个项目。一个是Silverlight，另一个是WCF。在WCF项目中，有一个类，我们在登录时分配所有会话变量。现在，我将一个现有的aspx项目（仅包含login.aspx和home.aspx）添加到同一解决方案中并添加了服务引用。现在aspx项目是启动项目。现在用户将从login.aspx页面而不是login.xaml页面登录。在登录时，我正在设置类中的所有会话变量。从登录页面我将用户重定向到主页。在主页中，用户可以导航到不同的silverlight页面。但是当我在silverlight页面之间导航时，我将所有会话变量都设为null / 0。我怎么解决这个问题？请帮帮我。

这是我们维护会话的WCF项目中的类。当我们登录时，我们为所有变量分配会话，并在需要时获取相同的内容。
public class ClsSessionMaintenance
{
public void assign_compdb(int mainlogin)
{
HttpContext.Current.Session["mainloginid"] = mainlogin;
}
public static int getmaindbuserid()
{
int loginId = Convert.ToInt32((string)HttpContext.Current.Session["mainloginid"]);
return loginId;
}
}
配置文件有问题吗？通过WCF服务中的方法，我能够在ClsSessionMaintenance类中成功分配会话。它很好，直到这里。成功登录后，我将用户重定向到HomePage.aspx，该主页具有HomeMaster主页。在HomeMaster页面中，有超链接，以便用户可以导航到不同的Silverlight xaml页面。但是在分配会话之后，我立即调用从ClsSessionMaintenance类获取会话的函数。但我得到会话值为O.为什么会发生？请帮帮我。
