.NET Wrapper for Windows Live Services (from LiveSide.net)
The fine folks over at the LiveSide.net are working on a .NET wrapper for Windows Live Services. According to Scott, they will be adding support for a number of services, but have started with the Live Photos API. Head over to Scott's post for much more info, including a code sample. Also, this is an opensource project, so you can check out the source code on CodePlex.
