Question

i m not sure that what im going to do is the right so i first of all tell you my issue. I have TFS as Bugtracking System and another system for tracking the worktime. I want that if a workitem status changes the other system changes the status too.

到目前为止，我所做的如下。

当我捕捉到WorkItemChangedEvent时，我为TFS web服务编写了一个插件。

 public EventNotificationStatus ProcessEvent(TeamFoundationRequestContext requestContext, NotificationType notificationType, object notificationEventArgs, 
                                                    out int statusCode, out string 
statusMessage, out ExceptionPropertyCollection properties)   
        {
            statusCode = 0;
            properties = null;
            statusMessage = String.Empty;
            try
            {
                if (notificationType == NotificationType.Notification && notificationEventArgs is WorkItemChangedEvent)
                {
                    WorkItemChangedEvent ev = notificationEventArgs as WorkItemChangedEvent;
                    EventLog.WriteEntry("WorkItemChangedEventHandler", "WorkItem " + ev.WorkItemTitle + " was modified");
                }

            }
            catch (Exception)
            {
            }
            return EventNotificationStatus.ActionPermitted;
        }

I droped the DLL in C:Program FilesMicrosoft Team Foundation Server 2010Application TierWeb ServicesinPlugins but i looks like the extension is never called. So nothing apears in the event log.

But if i try to debug the service like in this post http://geekswithblogs.net/jakob/archive/2010/10/27/devleoping-and-debugging-server-side-event-handlers-in-tfs-2010.aspx i cant hook on the process. So debugging does not work. Why i cant debug the service? And is there a better way to do this?

Answer 1

若要调试w3wp.exe进程，您需要以管理员身份运行Visual Studio。

From the menu, select Debug > Attach to process (or Ctrl-Alt-P)
Select Show processes from all users and Show processes in all sessions.
Find the w3wp.exe process that corresponds to your TFS Application Pool, and attach to it.

我注意到您正在使用EventLog.WriteEntry（）-您之前在代码中注册过事件源吗？为了避免注册（这需要管理员权限），您可以尝试使用TFS记录器：

TeamFoundationApplication.Log（“WorkItem”+ev.WorkItemTitle+“已修改”，0，System.Diagnostics.EventLogEntryType.Information）

不确定您是否修复了此问题，但在我看来，类中似乎缺少Subscription方法。

public Type[] SubscribedTypes()
{
    return new Type[1] {typeof(WorkItemChangedEvent)};
}

没有这个，你的插件永远不会被击中，因此你将无法调试。
