Visual Studios Get attachments, linked items, effort times for a work item

[michowl]

Given a VSTS work item id, I'd like to be able to get:

- lists of linked work items

- lists of attachments

- Effort Spend (estimated, remaining, completed)

Is there any update on when this could be accomplished? It would be incredibly helpful for me, especially the linked work items (User Story, Feature, Epic related to a task).
