生成的映射工作成功。但是,如果对工作流进行了修改并重新保存,则SourceLocationProvider仅从原始xaml映射
有没有办法强制SourceLocationProvider在引擎盖下使用的AttachedProperties进行更新
如果试图使用
WorkflowDesigner.Load(..)
则必须创建一个全新的WorkflowDesigner对象,因为WorkflowDesigner只能加载一次文件。如果可能,我希望避免此操作,因为它会丢失任何已设置的调试数据。对不起,我自己没有尝试过此操作,但是您可以从设计器的ModelChanged事件调用SourceLocationProvider.CollectMapping(…)吗?对不起,我自己没有尝试过此操作,但是您可以调用SourceLocationProvider.CollectMapping(…)从设计器的ModelChanged事件?使用反射,可以直接从调试服务本身获取所需的信息。以下解决方案对我有效,并在更新工作流后继续有效:
