Trying to keep up with the latest and greatest SDK's is sometimes a dizzying task but such as life when dealing with technology. That said, SDK v2.1 of the Windows Azure SDK for .NET was recently released. This is a major refresh of the Windows Azure SDK and it includes some great new features and enhancements. These new capabilities include:
All of these SDK enhancements are now available to start using immediately and you can download the SDK from the Windows Azure .NET Developer Center. Visual Studio’s Team Foundation Service has also been updated to support the SDK v2.1 release, and the SDK v2.1 features can now be used with it (including with automated builds + tests).
