TFS query for tasks with no parent

Question

I would like create a Flat list of work items query in TFS in which the results contain all of the specified PBI and Bug cases and any Task cases that have no parent.

It's that Task with no parent part that has me perplexed. I cannot see a way that I can do what seems so obvious such as (Parent Link Count = 0) because that attribute is not exposed to me though, strangely, some other link type counts are.

Any ideas?

Answer 1

Just change the query type to the Direct Links query, after this, make sure to choose the pull back option, to pull all work items with no match links. Eventually, the result again will be a flat list.
