Silverlight Application.InstallState - 不正确
我使用 Tim Heuer 在此处概述的 Silverlight 4 OOB 安装模式：
http://timheuer.com/blog/archive/2009/08/12/silverlight-out-of-browser-force-install-pattern.aspx
这是我的应用程序的 *Application_Startup* 方法：
private void Application_Startup(object sender, StartupEventArgs e)
{
//string _USERID = e.InitParams["UserAccount"];
if ((App.Current.InstallState == InstallState.Installed) && (!App.Current.IsRunningOutOfBrowser))
{
this.RootVisual = new Installed();
}
else if (!App.Current.IsRunningOutOfBrowser)
{
this.RootVisual = new Installer();
}
else
{
this.RootVisual = new MainPage();
}
ShowBusy(false);
}
问题是，即使应用程序已安装并运行 App.Current.InstallState 也会返回 NotInstalled 并且 App.Current.IsRunningOutOfBrowser 为 false - 所以我的控件 Installed 永远不会显示，它始终显示安装程序控件。
我的开发环境和部署环境都是这种情况。
我被这个问题难住了，有人有想法吗？
I'm using the pattern Tim Heuer outlines here for my Silverlight 4 OOB installation pattern:
http://timheuer.com/blog/archive/2009/08/12/silverlight-out-of-browser-force-install-pattern.aspx
Here is my app's *Application_Startup* method:
private void Application_Startup(object sender, StartupEventArgs e)
{
//string _USERID = e.InitParams["UserAccount"];
if ((App.Current.InstallState == InstallState.Installed) && (!App.Current.IsRunningOutOfBrowser))
{
this.RootVisual = new Installed();
}
else if (!App.Current.IsRunningOutOfBrowser)
{
this.RootVisual = new Installer();
}
else
{
this.RootVisual = new MainPage();
}
ShowBusy(false);
}
The problem is that even when the app is installed and running App.Current.InstallState returns NotInstalled and App.Current.IsRunningOutOfBrowser is false - so my control Installed never shows, it always show the Installer control.
This is the case in both my dev and deployed environments.
I'm stumped on this one, anyone have thoughts?

当浏览器处于隐私浏览模式时，我发现了此问题。
I have seen problems with this when the browser is in private browsing mode.

有同样的问题。
我听说这只有在应用程序经过代码签名后才能正常工作。不知道这是否属实，因为我无法测试验证。

UPDATE: Red Herring - refer comments
Have the same problem.
I've heard that this only works proper when the application has been code-signed. Don't know if this is true as I cannot test to verify.
