Last year I published an application called Product Manager. This application supports the product owner in scrum team to work with Visual Studio Online. It offers functionality to create new product backlog items, manage the backlog, review ideas and break down product backlog item in smaller, more detailed items. To build this app I used the TFS OData Services (tfsodata.visualstudio.com/). This offered OData service to some data of Visual Studio online. Unfortunately it wasn’t very completed with sometimes resulted in a bad user experience.
