I found templates in Azure DevOps it is great feature, but I can't find how to create templates of user story with childs (tasks). Is it really create user story from template with N childs (tasks)?
We have typical user story with 10 tasks. Now when we need new copy (for new device), I create user story and after create 10 task from templates.
By reference to this doc: Use templates to add and update work items, with work item templates, you can quickly create work items that have pre-populated values for your team's commonly used fields. However, the child items are not contained in work item template.
In the meanwhile, the Create copy of work item feature allows you to create copy of this template user story including its child work items. Thus you could use this feature to create multiple similar user stories with N childs (tasks).
BTW, there is an extension: 1-Click Child-Links to define Child links, or even to create child items, might be helpful, too.
Update>>When we use the Create copy of work item feature, the new work item will show a comment "Copied from ***", this is by design, but we can manually delete it, as below.
