我使用“Visual Studio的加载项”向导创建一个新的Addin项目,现在我正在尝试添加一些事件处理程序：
public void OnConnection(object application,ext_ConnectMode connectMode,object addInInst,ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
_applicationObject.Events.BuildEvents.OnBuildBegin += BuildEvents_OnBuildBegin;
_applicationObject.Events.BuildEvents.OnBuildDone += BuildEvents_OnBuildDone;
_applicationObject.Events.SelectionEvents.OnChange += SelectionEvents_OnChange;
_applicationObject.Events.DocumentEvents.DocumentOpened += DocumentEvents_DocumentOpened;
_applicationObject.Events.DocumentEvents.DocumentSaved += DocumentEvents_DocumentSaved;
}
但无论我做什么,我的处理程序都永远不会执行！ 我是盲人吗我必须做任何事情来注册这些处理程序,或者为什么不工作？ 解决方法
看来你是垃圾收集者的受害者.见：

private readonly BuildEvents _buildEvents;
private readonly SelectionEvents _selectionEvents;
private readonly DocumentEvents _documentEvents;
private readonly Events _events;
public void OnConnection(object application,ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
_events = _applicationObject.Events;
_buildEvents = _events.BuildEvents;
_buildEvents.OnBuildBegin += BuildEvents_OnBuildBegin;
_buildEvents.OnBuildDone += BuildEvents_OnBuildDone;
_selectionEvents = _events.SelectionEvents;
_selectionEvents.OnChange += SelectionEvents_OnChange;
_documentEvents = _events.DocumentEvents;
_documentEvents.DocumentOpened += DocumentEvents_DocumentOpened;
_documentEvents.DocumentSaved += DocumentEvents_DocumentSaved;
}
