对于具有自定义活动的 SharePoint Visual Studio 顺序工作流，我在共享点日志中收到以下错误。

自定义活动是通过组件类创建的。

我不确定为什么会出现这个错误？请帮忙！！！

问题是因为当我将组件类更改为顺序活动时，我有活动属性，例如“A”和“B”。然后我将此活动添加到 VS 工具箱。在这个阶段它工作正常。

现在，当我更改活动代码以将其属性更改为“A”和“C”时，我还删除了一个具有参数为“容器”对象的构造函数。

当我重新编译此活动并刷新其 DLL 时。在工作流设计器中，Activity 没有被刷新，即它的工具箱仍然指向旧的 dll。

为了解决这个问题，我关闭并再次打开 VS，VOILA 设计师现在正在使用新属性获取更新的 Activity。

这是我认为是 VS 工具箱的限制，尽管更新了 dll，但它没有被刷新。

谢谢！

您可以访问工作流的源 XAML 吗？查看是否包含“容器”对象，以及是否有必要将它放在那里。如果您可以删除它并且仍然让工作流正常运行，这可能会解决问题。
