推荐答案

您可以从代码导航到 Windows Phone 应用的起始页.

You can navigate to the start page of a Windows Phone app from code.

从 WMAppManifest 中删除DefaultTask"条目

从 WMAppManifest 中的DefaultTask"中删除 NavigationPage 属性，并在您的应用程序的 Launching 事件中使用类似于下面示例的内容在启动时导航到选择的页面.

Remove the NavigationPage attribute from the "DefaultTask" in WMAppManifest, and in the Launching event of your app use the something like the example below to navigate to the page of choice upon launch.

    private void Application_Launching(object sender, LaunchingEventArgs e)
    {
        if (registered)
        {
           ((App)Application.Current).RootFrame.Navigate(new Uri("/<your start page>.xaml", UriKind.Relative));
        }
        else
        {
           ((App)Application.Current).RootFrame.Navigate(new Uri("/<your registration page>.xaml", UriKind.Relative));
        }

    }

您只需要决定如何确定某人已经注册.

You just have to decide how you want to determine that someone already registered.
