我目前正在使用 RIA 服务试用 Silverlight。我正在实现一个简单的登录表单。我还使用了提供的身份验证域服务模板，该模板生成以下文件：

[EnableClientAccess]
public class AuthenticationDomainService : AuthenticationBase<User>
{
    // To enable Forms/Windows Authentication for the Web Application, 
    // edit the appropriate section of web.config file.
}

public class User : UserBase
{
    // NOTE: Profile properties can be added here 
    // To enable profiles, edit the appropriate section of web.config file.

    // public string MyProfileProperty { get; set; }
    public int DefaultRows { get; set; }
}

现在我可以在我的应用程序中毫无问题地登录/注销。在 Silverlight 应用程序中，登录后，该行：

WebContext.Current.User.IsAuthenticated;

返回真。

但是，我需要在会话中坚持这一点（即，当我使用 F5 重新加载页面时）。

目前，当页面重新加载时，我必须重新登录。

这是我的登录代码：

WebContext.Current.Authentication.Login(new LoginParameters(this.UserName, this.Password, true, string.Empty),
                    (LoginOperation loginOperation) =>
                    {
                        if (loginOperation.LoginSuccess)
                        {
                            NotificationMessage Message = new NotificationMessage(this, null, "CLOSE");
                            Messenger.Default.Send<NotificationMessage>(Message);
                        }
                    }, null);

Login 方法的第三个参数是 IsPersistent 参数。从 MSDN Docs 中，我认为将其设置为 true 时，下次加载页面时，用户仍然会登录。但是，事实并非如此。

Do I somehow need to read a cookie which has been set internally and then login in the background with the username/password provided by that cookie? Or is there some other magic at work here?

I hope somehow has already done this.

Thanks in advance

After going through the Silverlight Business Application template, I found this line of code:

WebContext.Current.Authentication.LoadUser(this.Application_UserLoaded, null);

A good place to call it is in the Application's Startup event inside App.xaml.cs. This will load the authenticated user from the server.

I thought I'd post this if anyone happens to stumble across the same problem.
