I'm editing a wiki page and trying to link to a work item but nothing popups up when I enter '#', why not?
VSTS Wiki now supports referencing work items using #. You can type # and reference an existing work item. This feature has just been completed and is still being deployed as I type.
Very soon, you will be able to link a wiki to a work item. Imagine this feature allowing you to track what % of your epic is completed when you refer each feature of the epic on your wiki page.
