我正在尝试构建用于工作流中的SharePoint 2010的自定义活动。在设计师中，我可以在“自定义活动”下的功能区中的“操作”下拉菜单中看到活动。然而，这个元素从来没有在设计中体现出来，我不知道如何调试这个问题。调试SharePoint 2010自定义活动
我曾尝试将一个Debugger.Break（）放入事件处理程序中，但这会导致应用程序事件日志中的条目An unhandled exception ('Launch for user') occurred in w3wp.exe [xxxx]. Just-In-Time debugging this exception failed with the following error: Not enough storage is available to complete this operation.此外，将调试程序附加到w3wp.exe进程不会在任何中断点上停止。
我已经打开了SharePoint 2010内部的详细日志记录（并且日志记录非常详细！），但它似乎没有包含任何有关该组件的信息或设计人员未加载组件的原因。
这是这个非常基本的活动的相关代码片段。我在这里做错了什么？

借助内置的跟踪，任何时候我尝试将活动添加到工作流设计器中，我看到的GetHashCode（）和equals（），并没有别的电话。
