无法部署和使用启用 WebORB 的 C# 程序

我尝试部署 WebORB .NET C# ASP.NET (C#.NET) 应用程序，但无法让它工作。它会成功运行，但它不会做任何事情，而且我感觉我犯了一些愚蠢的错误。我有一个 Flex 客户端，它应该读取来自 WebORB 服务器的数据，并且 WebORB 控制台显示 Flex 客户端已连接，因此该部分正常。 C#.net 服务器应用程序无法正常工作。

我在下面发布了 C#.asp 服务器应用程序代码，因为我相信客户端工作正常。该应用程序应捕获正在运行的计算机的 CPU 使用情况，并将其发送到 WEBORB 服务器以允许 Flex 客户端访问。该代码来自 WebORB 网站上提供的示例。

I have tried to deploy a WebORB .NET C# ASP.NET (C#.NET) application, but I am unable to get it to work. It will run successfully, but it doesn't do anything, and I get the feeling I am making some silly mistake.
I have a Flex client which should read the data coming from the WebORB server, and the WebORB console shows that the Flex client is connected so that part is fine. The C#.net server application is what is not working.

I have posted the C#.asp server application code below as I believe the client works fine. This application should capture the CPU usage of the machine it is running on, and send it to the WEBORB server to allow access by the Flex client. The code is from an example provided on the WebORB website.
