If you have used Windows Azure for any length of time, one thing you should have noticed is the rate of change. When I say change, I’m not referring to things being taken away either. The change is almost always improving what already exists or adding more capabilities. The new SDK adds support for the Visual Studio 2013 preview, as well as updates for managing and automating services in Visual Studio. Take a look at Scott Guthrie’s post about the SDK to get a better understanding of some of the changes.
You can get the latest SDK from the Development Center.
By the way, if you need a Windows Azure subscription, here is the link for a free trial.
