I'm creating a workflow service in VS2010. I'm looking specifically to add a PolicyActivity to my designer, but I don't see it in the Toolbox. In fact, it seems that there are many activities missing. I see the following groups with 40 total available activities:

控制流

流程图

消息传递

运行时

原语

交易

收藏

错误处理

迁移

如果我右键单击工具箱，然后单击选择项目"，则会在System.Workflow.Components选项卡上检查所有组件(包括我需要的组件:策略).这可能是怎么回事?

If I right-click the toolbox and hit Choose Items, on the System.Workflow.Components tab all of the components are checked (including the one I need: Policy). What could be going on here?
