这里：
有没有办法在 Visual Studio 2008 中指定大纲默认值，以便打开文件时默认折叠成员？
..我可以找到一个编程插件的例子..但不幸的是它没有编译:-(
错误 1
“CollapsedMembers.Connect”不包含“_openHandler”的定义，并且找不到接受“CollapsedMembers.Connect”类型的第一个参数的扩展方法“_openHandler”（您是否缺少 using 指令或程序集引用？）
D:\CollapsedMembers\Connect.cs 77 18 CollapsedMembers
实际上那里没有 _openHandler。我已经尝试了所有的 .NET Framework 版本，但不幸的是没有成功。
在 OnOpenHandler.cs 我实现了 OnOpenHandler：
namespace CollapsedMembers
{
internal class OnOpenHandler
{
DTE2 _application = null;
EnvDTE.Events events = null;
EnvDTE.DocumentEvents docEvents = null;
... and so on...
有人可以帮忙吗？
