    copied!<p>I've been fooling around with the HttpListenter stuff found at: </p> <p><a href="http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/system.net.httplistener.aspx</a></p> <p>It works great on a standard console app, but I'm trying to get it working as a windows service. Application Logs show that when the service starts up, it fails on the HttpListener.Start() method. I'm pretty stumped as to why this might happen.</p> <p>Here's the class (proof of concept quality here :)</p> <pre><code>public class Server { public Server() { var thread = new Thread((Start)); thread.Start(); } public static void Start() { while(Listen()) { } } private static bool Listen() { var prefixes = new[] {"http://192.168.0.7/"}; if (!HttpListener.IsSupported) { Console.WriteLine ("Windows XP SP2 or Server 2003 is required to use the HttpListener class."); return false; } // URI prefixes are required, // for example "http://contoso.com:8080/index/". if (prefixes == null || prefixes.Length == 0) throw new ArgumentException("prefixes"); // Create a listener. HttpListener listener = new HttpListener(); // Add the prefixes. foreach (string s in prefixes) { listener.Prefixes.Add(s); } listener.Start(); //THIS FAILS IN WINDOWS SERVICE AS LOCAL SYSTEM //Console.WriteLine("Listening..."); //// Note: The GetContext method blocks while waiting for a request. //HttpListenerContext context = listener.GetContext(); //HttpListenerRequest request = context.Request; //// Obtain a response object. //HttpListenerResponse response = context.Response; //// Construct a response. //string responseString = "&lt;HTML&gt;&lt;BODY&gt; " + DateTime.Now + "&lt;/BODY&gt;&lt;/HTML&gt;"; //byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString); //// Get a response stream and write the response to it. //response.ContentLength64 = buffer.Length; //System.IO.Stream output = response.OutputStream; //output.Write(buffer,0,buffer.Length); //// You must close the output stream. //output.Close(); //listener.Stop(); return true; } } </code></pre> <p>Relavent Logs: Error:</p> <pre><code>Application: Stout.Workers.Service.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.
