远程过程调用失败(The remote procedure call failed)

 这是我的第一篇文章，所以请对我很轻松:) 
 
 我正在为Facebook SDK做一个教程 ，我正在尝试从Windows Phone XAML应用程序登录到facebook服务。 当我按照教程的步骤操作时，它工作正常，并点击登录按钮登录，但当我尝试自动执行此操作时，我收到错误。 
 
 该代码使用WebAuthenticationBroker，调用WebAuthenticationBroker.AuthenticateAndContinue(LoginUrl); 
 
 当我尝试将该代码放在Loaded事件中时 
 
private void Page_Loaded(object sender, RoutedEventArgs e)
{
    if (this.fbHelper.AccessToken == null)
    {
         WebAuthenticationBroker.AuthenticateAndContinue(LoginUrl); //throws error
    }
    else
    {
        GetUserInfo();
    }
}
 
 我收到以下错误： 
 
 
 
 远程过程调用失败。 （HRESULT异常：0x800706BE） 
 
 
 我认为问题是页面尚未准备好执行逻辑，但我真的不知道我应该在哪里放置代码？ 

This is my first post, so please be easy on me :)
 
I am doing a tutorial for Facebook SDK, and I am trying to login to the facebook service from a Windows Phone XAML application. It works fine when I follow the steps of the tutorial, and hit the login button to log in, but when I am trying to automate this, I get an error.
 
The code uses WebAuthenticationBroker, calling WebAuthenticationBroker.AuthenticateAndContinue(LoginUrl);
 
When I try to put that code inside Loaded event
 
private void Page_Loaded(object sender, RoutedEventArgs e)
{
    if (this.fbHelper.AccessToken == null)
    {
         WebAuthenticationBroker.AuthenticateAndContinue(LoginUrl); //throws error
    }
    else
    {
        GetUserInfo();
    }
}
 
I get the following error:
 
 
 
The remote procedure call failed. (Exception from HRESULT: 0x800706BE)
 
 
I think the problem is that the page is not ready yet to perform the logic, but I don't really know where should I put the code?
