使用TFS 2010 API订阅WorkItem事件

Question

I'm trying to write some code that monitors the TFS WorkItems on my local workstation but at the moment I'm having problems getting the events to fire.

I have subscribed to FieldChange event of WorkItem but it doesn't fire when I change/update any workitem.

The code below is a console application that I think should work,bu it doesn't . Does anyone know how to successfully subscribe to these events?

Any help in this matter is appreciable .

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.TeamFoundation.Client;
using System.Net;
using Microsoft.TeamFoundation.VersionControl.Client;
using Microsoft.TeamFoundation.WorkItemTracking.Client;
using Microsoft.TeamFoundation.Framework.Client;

namespace TFSEvents
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Uri serverUri = new Uri(@"http://tfs");
                string username, password;
                Console.WriteLine("Enter Username:");
                username = Console.ReadLine();
                Console.WriteLine("Enter password:");
                password = ReadPassword();
                NetworkCredential cred = new NetworkCredential(username, password);
                TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(serverUri, cred);
                tfs.EnsureAuthenticated();
                IEventService vs = tfs.GetService<IEventService>();
                var wiww = tfs.GetService<WorkItemStore>();
                var wi = wiww.GetWorkItem(4671);
                wi.FieldChanged += new WorkItemFieldChangeEventHandler(changeHandler);
                var x = vs.GetAllEventSubscriptions().ToList();
                Console.WriteLine("Press \'q\' to quit.");
                while (Console.ReadLine() != "q") ;
            }
            catch (Exception e)
            {

            }
        }

        private static void changeHandler(object o, WorkItemEventArgs e)
        {
            Console.WriteLine(e.Field);
        }
   }
}

You cant handle WorkItem events in that way, it will only work for a single instance. There are only a fixed set of events you can handel:

And you need an eventhandler to use them:

UPDATE

If you don't want to use BisSubscribe.exe you can create a subscription using the API. If you check my bad code on http://tfseventhandler.codeplex.com/SourceControl/latest#RELEASE/v1.3/RDdotNet.TeamFoundation/Managers/TeamServerManager.vb you should see a "RegisterEvent()" method that will do the job.
