Notes for developing sequential workflows

1. the lifecycle of each task, including four activities: createtask, ontaskchanged, completetask, and deletetask.
2. The same correlationtoken attribute and taskid attribute must be set for the activity of the same task.
3. Different correlationtoken attributes and taskid attributes should be set for different tasks.
4. The owneractivityname of the live worker and the parent container name of the live worker. We recommend that you set it to the minimum parent container name of the live worker, especially when the live worker is included in the while live worker.
5. workflowproperties:
This attribute contains the workflow start information, such as the person who starts the workflow, list items, and time.
6. correlationtoken:
Correlation token maps several associated active tokens to the identifiers of the same set. It does not act as the groupid attribute of the radiobuttion component in some programming languages. Similarly, do not specify the same correlationtoken for the job live token and job flow live token.
7. Set the afterproperties attribute of ontaskchanged to the same variable as the taskproperties attribute of the createtask living condition (the purpose is to save the user's modifications to the task by default ).
