On Friday we published v2.2.0 of the OData Service for Team Foundation Server. This is a significant release which includes several bug fixes, feature enhancements, and performance optimizations based on the feedback we have received from beta testers. Please view the changelog for details on what is new in this release.
A new sample application is also available and showcases how to use the OData Service from a Windows Phone 8 application. You can download the on-premises OData Service for Team Foundation Server v2.2.0 along with sample applications for Windows 8 and Windows Phone 8 at http://aka.ms/tfsodata. You can access the hosted OData Service for Team Foundation Service at https://tfsodata.visualstudio.com which now includes the same updates as the on-premises package.
