For fields like 'System.Description','System.History','System.State','System.Title', their paths are relatively self explanatory.
Given the documentation here:
https://www.visualstudio.com/en-us/docs/integrate/api/wit/work-items#update-a-field
Where would something like 'Acceptance Criteria' for product backlog items be? I see description in this documentation:
https://msdn.microsoft.com/en-us/library/microsoft.teamfoundation.workitemtracking.client.workitem(v=vs.120).aspx?f=255&MSPPError=-2147217396&cs-save-lang=1&cs-lang=csharp#code-snippet-1
But nothing about some of the other fields. Is there a way to figure this out?
