我在具有自定义活动的SharePoint Visual Studio顺序工作流的sharepoint日志中遇到以下错误。
自定义活动是通过Component Class创建的。
我不确定为什么会出现这个错误？请帮忙!!!

问题是因为当我将Component类更改为Sequential Activity时，我有Activity属性，例如'A'＆amp; 'B'。然后我将此活动添加到VS工具箱。在这个阶段它运作良好。
现在，当我更改活动代码以将其属性更改为“A”和＆amp; 'C'和我还删除了一个构造函数，其参数为'Container'对象。
当我重新编译此Activity并刷新其DLL时。在工作流设计器中，Activity没有刷新，即它的工具箱仍指向旧的dll。
Resolve 为此我关闭并再次打开VS，VOILA设计师现在正在使用新属性更新活动。
这是我认为VS工具箱的限制，即使dll更新该活动，它也不会刷新。
谢谢！

您可以访问工作流程的源XAML吗？查看是否包含“Container”对象，以及是否需要将其包含在那里。如果您可以删除它并仍然正常运行工作流程，这可能会解决问题。
