在VS2005的工具箱中增加SharePoint的活动

今天从微软网站下载安装了ECM Start Kit Beta版，装完后在VS2005中并没有自动加载SharePoint的活动。ECM Start Kit的随机文档中提示如下方法：
1) In workflow design mode, right click in the Toolbox.  Select “Shoose Items”。
2) In the activities tab, browse for the dll in %programfiles%/Common Files/Microsoft Shared/web server extensions/12/ISAPI/Microsoft.SharePoint.WorkflowActions.dll.
3) (optional) By default, all activities here are selected.  You can deselect activities that you do not wish to see.

需要注意的是，要首先建一个SharePoint的Tab，然后再在其中加载活动。
