tf80006 - Can't publish project plan to TFS

Problem:

tf80006 - Can't Publish from Project to TFS.
TF80006: Team Foundation needs a work item type to publish work items.

Solution:

One of gotchas that bit me was that I did not set the Work Item Type in Project. Once I set it to 'Task' I was able to publish my schedule to TFS.
