Graph API: Add OData $filter support for Planner Tasks (e.g. /me/planner/tasks)
Currently it's not possible to filter tasks using the Microsoft Graph REST endpoints for Planner.
E.g. this does NOT work, but should:
Currently the filter parameter will be ignored, all tasks are returned instead.
We are currently discussing this in our planning meetings. This is not currently agreed to be placed on our backlog as yet. ^JT
Given that this is now no longer in beta (i.e. it is available under /v1.0/) - it would really be nice if $filter actually worked.
It seems that $orderby and $top also do not work.. so therefore it isn't really possible to workaround the lack of $filter. Attempting to retrieve all tasks and filter on the client side is just not feasible for a production application.
