We're currently using Visual Studio 2015 Community and Team Foundation Server 2010.
Are there any open-source C# projects that connect to TFS and display the workitems as a scrumboard?
I remember looking for one back when TFS2010 was the current version and could find none that worked well.
As jessehouwing mentioned, if possible, upgrade to TFS 2015 (or better yet, Visual Studio Team Services, which is TFS in the cloud) to get a really useful Scrum board and Kanban board.
