Updating Task level custom fields
问题 Using CSOM I can see how to use the SetCustomFieldValue method to update custom fields associated to a Project, but is it not possible to do this for a task within Project Online? I don't see anything that would allow this but it does list in the documentation this should be possible. Thanks! 回答1: Have you looked at this thread?
